多项式Liénard方程的中心条件
Center conditions for polynomial Liénard equation
摘要
Abstract
Necessary and sufficient conditions are studied for the coeffcients of polynomials f(x) and g(x)such that the Liénard equation +f(x)+g(x)=0 has non-degenerate centers, a algorithm to calculate the center conditions with elimination theory is presented.关键词
