Outline of Final Research Achievements |
For constructing the ED model, we show the asymptotic stability of the blood and lymph model of infectious diseases in a body and the reaction diffusion partial differential equations with finite delay. Moreover, we study the existence theorem of almost periodic solutions and the asymptotic stability of control model with a time lag of testosterone secretion, announced at the International Conference of Poland and submitted a paper. In 2016, Osaka Prefecture University, Professor Matsunaga in joint International Conference on Difference Equation and Applications held in Osaka and, the Satellite Conference held in the institution, Okayama University of science, in Okayama.
