A Periodic Solution of the Generalized Forced Liénard Equation

الملخص EN

We consider the generalized forced Liénard equation as follows: ( ϕ p ( x ′ ) ) ′ + ( f ( x ) + k ( x ) x ′ ) x ′ + g ( x ) = p ( t ) + s .

By applying Schauder's fixed point theorem, the existence of at least one periodic solution of this equation is proved.
