Abstract: In this paper we prove the existence of nontrivial quasi-homoclinic solutions for the damped p-Laplacian differential equation (|u′|p−2u′)′ + c|u′|p−2u′ − a(t)|u|p−2u + f(t, u) = 0, t ∈ R, where p ≥ 2, c ≥ 0 is a constant and the functions a and f are continuous and not necessarily periodic in t. Using the Mountain-Pass Theorem, we obtain the existence of positive homoclinic solution in both cases sub-quadratic and super-quadratic.
Keywords: quasi-homoclinic solution; the (PS)-condition; mountain pass theorem; damped p-Laplacian differential equation.
