岡山大学環境理工学部 Acta Medica Okayama 1341-9099 6 1 2001 捕食系の感染症数理モデルにおける進行波解の速度 17 23 EN Tsuyoshi Kajiwara Tomoki Okita In this paper we construct a simple mathematical model for infectious disease in a pradator-prey system, and study the speeds of travelling wave solutions of this model. We present a method of estimation of speeds and make a numerical study about this matter. No potential conflict of interest relevant to this article was reported.
