Existence of homoclinic orbit in generalized Liénard type system

摘要

The object of this paper is to study the existence and nonexistence of an important orbit in a generalized Liénard type system. This trajectory is doubly asymptoticto an equilibrium solution, i.e., an orbit which lies in the intersection of the stable andunstable manifolds of a critical point. Such an orbit is called a homoclinic orbit..
