Let δ be a derivation on R. A ring R is called δ-quasi-Baer (resp. quasi-Baer) if the right annihilator of every δ-ideal (resp. ideal) of R is generated by an idempotent of R. In this note first we give a positive answer to the question posed in Han et al. [7], then we show that R is δ-quasi-Baer iff the differential polynomial ring S = R[x; δ] is quasi-Baer iff S is δ‾-quasi-Baer for every extended derivation δ‾ on S of δ. This results is a generalization of Han et al. [7], to the case where R is not assumed to be δ-semiprime.

We show that it holds for a more general family of rings, that is, for connected commutative rings whose quotient ring by the corresponding Jacobson radical is von Neumann regular and locally uniform. Some properties of the (connected) separable closure of such rings are also given as an application of this result.

Using a simple spectral property of compound matrices, a necessary and sufficient condition for stability of the quasicyclic complex vector functional equation considered is proved.

One is to represent a unital real commutative Banach algebra A as an algebra of continuous functions on the unital homomorphism space ΦA. The other is to represent A as an algebra of continuous sections on the maximal ideal space MA. In this note, we point out that similar theorems for non-unital case hold and show that two representation theorems are essentially identical.

Moreover, we also discuss an application of this result to the study of the p-rank of cyclic coverings of curves in positive characteristic. en-copyright= kn-copyright= en-aut-name=HoshiYuichiro en-aut-sei=Hoshi en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Research Institute for Mathematical Sciences, Kyoto University kn-affil= en-keyword=abelian variety kn-keyword=abelian variety en-keyword=torsion point kn-keyword=torsion point en-keyword=curve kn-keyword=curve en-keyword=p-rank kn-keyword=p-rank END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=1 article-no= start-page=73 end-page=76 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Note on Zero Commutative and Duo Rings en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HabebJebrel M. en-aut-sei=Habeb en-aut-mei=Jebrel M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Yarmouk University END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=1 article-no= start-page=153 end-page=160 dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=200001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Note on the Degenerate Morse Inequalities en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper we give an analytic proof of the degenerate Morse inequalities in the spirit of E.

Conversely, for each set of points providing a balanced configuration, there is a corresponding three-parameter family of doubly periodic minimal surfaces. In this note we derive a differential equation that is equivalent to the balance equations for doubly periodic minimal surfaces. This allows for the generation of many more solutions to the balance equations, enabling the construction of increasingly complicated surfaces. en-copyright= kn-copyright= en-aut-name=ConnorPeter en-aut-sei=Connor en-aut-mei=Peter kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Mathematical Sciences, Indiana University South Bend kn-affil= en-keyword=minimal surfaces kn-keyword=minimal surfaces en-keyword=doubly periodic kn-keyword=doubly periodic en-keyword=balance equations kn-keyword=balance equations END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=2 article-no= start-page=115 end-page=116 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=198112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A note on commutative separable algebras.

Realizing the triangular lattice into R2 appropriately, we observe that the Euclidean distance in R2 naturally appears in the asymptotics. We characterize this realization from a geometric view point of Kotani-Sunada’s standard realization of crystal lattices. As a corollary of the main theorem, we obtain that the transition semigroup generated by the non-symmetric random walk approximates the heat semigroup generated by the usual Brownian motion on R2. en-copyright= kn-copyright= en-aut-name=IshiwataSatoshi en-aut-sei=Ishiwata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawabiHiroshi en-aut-sei=Kawabi en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TeruyaTsubasa en-aut-sei=Teruya en-aut-mei=Tsubasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Mathematical Sciences, Faculty of Science Yamagata University affil-num=2 en-affil= kn-affil=Department of Mathematics, Faculty of Science Okayama University affil-num=3 en-affil= kn-affil=The Okinawa Kaiho Bank, Ltd. en-keyword=Non-symmetric random walk kn-keyword=Non-symmetric random walk en-keyword=asymptotic expansion kn-keyword=asymptotic expansion en-keyword=triangular lattice kn-keyword=triangular lattice en-keyword=standard realization kn-keyword=standard realization END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=1 article-no= start-page=155 end-page=165 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=AN EXPLICIT PSp4(3)-POLYNOMIAL WITH 3 PARAMETERS OF DEGREE 40 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We will give an explicit polynomial over ℚ with 3 parameters of degree 40 as a result of the inverse Galois problem.

We analyze asymptotic properties of its Green function with spectral parameters in the unphysical sheet. As an application, we discuss the lower bound on resonance widths for scattering by two magnetic fields with compact supports at large separation. The bound is evaluated in terms of backward scattering amplitudes by a single magnetic field. A special emphasis is placed on analyzing how a trajectory oscillating between two magnetic fields gives rise to resonances near the real axis, as the distance between two supports goes to infinity. We also refer to the relation to the semiclassical resonance theory for scattering by two solenoidal fields. en-copyright= kn-copyright= en-aut-name=TamuraHideo en-aut-sei=Tamura en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Department of Mathematics, Okayama University en-keyword=Aharonov-Bohm Hamiltonian kn-keyword=Aharonov-Bohm Hamiltonian en-keyword=Green function kn-keyword=Green function en-keyword=magnetic Schrödinger operator kn-keyword=magnetic Schrödinger operator en-keyword=scattering amplitude kn-keyword=scattering amplitude en-keyword=resonance width kn-keyword=resonance width END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=1 article-no= start-page=59 end-page=72 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Absolute continuity of the representing measures of the transmutation operators attached to the root system of type BC2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We prove in this paper the absolute continuity of the representing measures of the transmutation operators Vk, tVk and VkW, tVkW associated respectively to the Cherednik operators and the Heckman-Opdam theory attached to the root system of type BC2. en-copyright= kn-copyright= en-aut-name=TrimẻcheKhalifa en-aut-sei=Trimẻche en-aut-mei=Khalifa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Mathematics Faculty of sciences of Tunis University kn-affil= en-keyword=Transmutation operators kn-keyword=Transmutation operators en-keyword=Absolute continuity of the representing measures kn-keyword=Absolute continuity of the representing measures en-keyword=Cherednik operators kn-keyword=Cherednik operators en-keyword=Heckman-Opdam theory kn-keyword=Heckman-Opdam theory END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=1 article-no= start-page=141 end-page=145 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=199801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Actions on Spaces of Polynomials en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YamaguchiKohhei en-aut-sei=Yamaguchi en-aut-mei=Kohhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=University of Electro-Communications en-keyword=homotopy groups kn-keyword=homotopy groups en-keyword=action kn-keyword=action en-keyword=polynomial kn-keyword=polynomial END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=1 article-no= start-page=17 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=200101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Adjoint Orbit Types of Compact Exceptional Lie Group G2 in its Lie Algebra en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MiyasakaTakashi en-aut-sei=Miyasaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Takatoh High School END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=1 article-no= start-page=35 end-page=81 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Affine Kac-Moody Groups as Twisted Loop Groups obtained by Galois Descent Considerations en-subtitle= kn-subtitle= en-abstract= kn-abstract=We provide explicit generators and relations for the affine Kac-Moody groups, as well as a realization of them as (twisted) loop groups by means of Galois descent considerations.

The system consists of four scatters, two obstacles and two scalar potentials with compact support, which are largely separated from one another. The obstacles by which the magnetic fields are completely shielded are vertically placed between the supports of the two potentials. The system yields a two dimensional model of a toroidal scattering system in three dimensions. The resonances are shown to be generated near the real axis by the trajectories trapped between two supports of the scalar potentials as the distances between the scatterers go to infinity. We analyze how the AB effect influences the location of resonances. The result heavily depends on the width between the two obstacles as well as on the magnetic fluxes. The critical case is that the width is comparable to the square root of the distance between the supports of the two potentials. en-copyright= kn-copyright= en-aut-name=TamuraHideo en-aut-sei=Tamura en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Department of Mathematics, Okayama University en-keyword=Aharonov–Bohm effect kn-keyword=Aharonov–Bohm effect en-keyword=magnetic Schrödinger operator kn-keyword=magnetic Schrödinger operator en-keyword=resonances kn-keyword=resonances END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue=1 article-no= start-page=41 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Aharonov--Bohm effect in resonances of magnetic Schrödinger operators in two dimensions II en-subtitle= kn-subtitle= en-abstract= kn-abstract=We study the Aharonov–Bohm effect (AB effect) in quantum resonances for magnetic scattering in two dimensions. The system consists of four scatters, two obstacles and two scalar potentials with compact support, which are largely separated from one another. The obstacles by which the magnetic fields are completely shielded are horizontally placed between the supports of the two potentials. The fields do not influence particles from a classical mechanical point of view, but quantum particles are influenced by the corresponding vector potential which does not necessarily vanish outside the obstacle. This quantum phenomenon is called the AB effect. The resonances are shown to be generated near the real axis by the trajectories trapped between two supports of the scalar potentials as the distances between the scatterers go to infinity. We analyze how the AB effect influences the location of resonances. The result is described in terms of the backward amplitudes for scattering by each of the scalar potentials, and it depends heavily on the ratios of the distances between the four scatterers as well as on the magnetic fluxes of the fields. en-copyright= kn-copyright= en-aut-name=TamuraHideo en-aut-sei=Tamura en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1

Let F be a field of char(F) = p > 0 and G an abelian group with p-component Gp of cardinality at most ℵ1 and length at most ω1. The main affirmation on the Direct Factor Problem is that S(FG)/Gp is totally projective whenever F is perfect. This extends results due to May (Contemp. Math., 1989) and Hill-Ullery (Proc. Amer. Math. Soc., 1990). As applications to the Isomorphism Problem, suppose that for any group H the F-isomorphism FH ≅ FG holds. Then if Gp is totally projective, Hp ≅ Gp. This partially solves a problem posed by May (Proc. Amer. Math. Soc., 1988). In particular, H ≅ G provided G is p-mixed of torsion-free rank one so that Gp is totally projective. The same isomorphism H ≅ G is fulfilled when G is p-local algebraically compact too. Besides if Fp is the simple field with p-elements and Gp FpH is a coproduct of torsion complete groups, FpH ≅ FpG as Fp Fp-algebras implies Hp ≅ Gp. This expands the central theorem obtained by us in (Rend. Sem. Mat. Univ. Padova, 1999) and partly settles the generalized version of a question raised by May (Proc. Amer. Math. Soc.,1979) as well. As a consequence, when Gp is torsion complete and G is p-mixed of torsion-free rank one, H ≅ G. Moreover, if G is a coproduct of p-local algebraically compact groups then H ≅ G. The last attainment enlarges an assertion of Beers-Richman-Walker (Rend. Sem. Mat. Univ. Padova, 1983). Each of the reported achievements strengthens our statements in this direction (Southeast Asian Bull. Math., 2001-2002) and also continues own studies in this aspect (Hokkaido Math. J., 2000) and (Kyungpook Math. J., 2004).
