Certain Metrics on R⁴+(II)

This paper is a continuation of the one with the same title([4]), in which we obtained a special solution for a system of differential equations on metric tensors on R⁴+ satisfying the Einstein condition for Case I generalizing the Ot-metric: in Theorem 1, and proved that there exist no solutions for Case II in Theorem 2. In this work, we shall show that we can obtain more general solutions for Case I which depend on the latitude parameter. We use the results in [4], so the section numbers start from 5. 1. Preliminaries and curvature tensor 2. Ricci tensor 3. Solutions for Case I 4. Analysis and a conclusion for Case II
