應yl7703永利官網(wǎng)王智誠教授和張亮博士的邀請,中國科學技術大學張磊博士將于2018年3月9日至3月13日訪問蘭州大學,期間將舉辦專題學術報告。
報告題目:Basic reproduction ratios for periodic abstract functional differential equations報告摘要:The basic reproduction ratio is an important parameter in population biology. Mathematically, we hope to prove that R_0-1 can determine the local stability of the zero steady state. Such a theory has been developed for many classes of models including autonomous and time periodic ODEs and reaction-diffusion models with or without time delay. In this talk, we will discuss the such a theory to abstract functional differential equations whose solution maps may be non-compact. The principle eigenvalue theory for a positive operator is the main tools in this project.
時 間:3月12日下午 4:00.
地 點:齊云樓815
歡迎廣大師生光臨!
