数学与大数据学院邀请华中师范大学黄继才教授作学术报告报道

       应佛山科学技术学院数学与大数据学院院长戎海武教授和吴楚芬教授的邀请，华中师范大学黄继才教授于6月23日下午3点，在腾讯会议(ID 486-342-037)上开展了关于“Bifurcations in the modified RM equation: from asymptotic dynamics to transient dynamics”的学术报告。吴楚芬教授主持线上学术会议，学院微分方程方向老师及研究生参会。整个线上报告精彩纷呈，理论与应用相结合，引起了师生热烈的反响。 

       报告简介：In this talk, we take Rosenzweig-MacArthur (RM) model with generalist predator as an example in a constant or changing environment. When the environment is fixed, we provide a more easily verifiable classification to determine the types and codimension of nilpotent singularities in a general planar system. Second, by using some algebraic methods, we show that the highest codimension of a nilpotent focus is 4 and the sample RM model with generalist predator can exhibit nilpotent focus bifurcation of codimension 4. When the environment is changing, we study the impact of the rate and intensity of a nonlinear environmental change on dynamics. It is based on a joint work with Min Lu and Professor Hao Wang.
