摘要
讨论了一类广义Liénard型系统.x=p(y)k(x),.y=-f(x,y)p(y)q(y)-g(x)h(y)非零周期解的存在性和不存在性,给出了非零周期解的存在和不存在的一类充分条件.
This paper deals with the existence and non-existence of nonzero periodic solution for general system of Liénard type{.↑x=p(y)k(x),;.↑y=-f(x,y)p(y)q(y)-g(x)h(y) and gives some sufficient conditions which ganrantee the existence and non-existence of nonzero periodic solution for above differential system.
