New results on the existence and uniqueness of periodic solutions for Lienard type p-Laplacian equation

摘要

By means of topological theory, a class of Lienard type p-Laplacian equation with a deviating argument of the form (φ_p(x'(t)))' + f(x(t))x' (t) + β(t)g(x(t - ι(t))) = e(t) is studied. The authors establish some criteria to guarantee the existence and uni
