报告题目：Results and openproblems on the algebraic limit cycles of the planar polynomial differentialsystems
报告摘要：In this talk we summarize someresults and open problems on the algebraic limit cycles of the planarpolynomial differential systems. More precisely, (i) we study the maximumnumber of algebraic limit cycles of the polynomial differential differentialsystems of degree n; (ii) we show how to use the algebraic limit cycles forproving that any finite configuration of limit cycles can be realized by somepolynomial differential system; (iii) we provide the maximum number ofalgebraic limit cycles formed by circles that a polynomial differential systemof degree n can exhibit; (iv) we study the algebraic limit cycles of the polynomialdifferential systems of degree 2.
