2025年学术讲座预告（No.40）聊城大学刘兴副教授做报告 报告题目：Numerical threshold stability of a nonlinear age-structured reaction diffusion heroin transmission model报告摘要：This talk focuses on the numerical threshold stability of a nonlinear age-space structured heroin transmission model. A semi-discrete system is established by spatial domain discretization of the original nonlinear age-space structured model. A threshold value is proposed ... 2025年10月14日（星期二）13:00 线上腾讯会议：713-772-689 【查看详情】

2025年学术讲座预告（No.39）哈尔滨工业大学杨占文副教授做报告 报告题目：Numerical Analysis for Population Models with Logistic Growth Rate报告摘要：In this talk we review the background information of several population models with Logistic growth rate, including ordinary differential equations, age-structured HIV models and reaction-diffusion Fisher models. For these models, a linearly implicit approach is introduced to the Logistic growth, which ensures... 2025年10月14日（星期二）15:00 线上腾讯会议：883-619-642 【查看详情】

2025年学术讲座预告（No.38）云南师范大学范文文教授做报告 报告题目：The classification of complete regular dessins报告摘要：A complete dessin is an orientable map with underlying graph being a complete bipartite graph, which is said to be regular if all edges are equivalent under the group of color- and orientation- preserving automorphisms. Regular dessins possess excellent geometric and algebraic properties, which have been involved in numerous inte... 2025年10月2日（星期四）9:30 365电子娱乐官方网站数学与统计学院3406 【查看详情】
