應(yīng)佛山大學(xué)數(shù)學(xué)學(xué)院副院長吳楚芬教授的邀請,,上海師范大學(xué)周鵬教授于10月17日下午1點(diǎn),在騰訊會議(590560277)開展了題為“On a Lotka-Volterra competitive patch model”的學(xué)術(shù)報(bào)告,。吳楚芬教授主持線上學(xué)術(shù)報(bào)告會,,學(xué)院微分方程方向老師及研究生參會,。整個(gè)學(xué)術(shù)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)告后,周鵬教授針對研究生和年輕博士老師們提出的疑問,,開展了專門的輔導(dǎo),,并確定了合作的研究內(nèi)容。
報(bào)告簡介:A Lotka-Volterra patch model describing the competition between two aquatic species is investigated, where organisms are supposed to take both random and advective movements. The global dynamics is determined in different settings of parameters, where sufficient analysis on the principal eigenvalue is performed to determine the local dynamics of the boundary equilibria and a technical approach is developed to establish the nonexistence of any positive equilibrium for any number of patches. This work can be seen as a further development of a series of works on the corresponding space-continuous PDE model.
周鵬教授簡介:上海師范大學(xué)數(shù)學(xué)系教授,博士生導(dǎo)師,。2015年獲上海交通大學(xué)理學(xué)博士,。2015-2017年受加拿大北大西洋數(shù)學(xué)科學(xué)研究協(xié)會(AARMS)資助從事博士后研究。主要從事微分方程與動力系統(tǒng)領(lǐng)域的研究,,圍繞無窮維競爭系統(tǒng)全局動力學(xué)做出系列工作,,部分結(jié)果發(fā)表在JMPA,JFA,,JDE,,SIMA,SIAP等國際數(shù)學(xué)期刊,。主持國家自然科學(xué)基金委優(yōu)青項(xiàng)目,、面上項(xiàng)目,上海市科委基礎(chǔ)研究項(xiàng)目等,。曾入選上海市東方學(xué)者特聘教授及跟蹤計(jì)劃,。
