數(shù)學(xué)與大數(shù)據(jù)學(xué)院邀請華中師范大學(xué)黃繼才教授作學(xué)術(shù)報(bào)告報(bào)道

       應(yīng)佛山科學(xué)技術(shù)學(xué)院數(shù)學(xué)與大數(shù)據(jù)學(xué)院院長戎海武教授和吳楚芬教授的邀請,，華中師范大學(xué)黃繼才教授于6月23日下午3點(diǎn)，在騰訊會(huì)議(ID 486-342-037)上開展了關(guān)于“Bifurcations in the modified RM equation: from asymptotic dynamics to transient dynamics”的學(xué)術(shù)報(bào)告,。吳楚芬教授主持線上學(xué)術(shù)會(huì)議,，學(xué)院微分方程方向老師及研究生參會(huì),。整個(gè)線上報(bào)告精彩紛呈，理論與應(yīng)用相結(jié)合，引起了師生熱烈的反響,。 

       報(bào)告簡介：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.
