Oscillation criteria for generalized Liénard type system
Abstract
In this work we use qualitative theory of differential equations to study the qualitative behavior of the solutions of a generalized Liénard system. Under quite general assumptions we present some sharp conditions under which thesolutions of the system are oscillatory. Some examples are presented to illustrate our results.
