Jiang, Mei Yue, A LandesmanLazer Type Theorem for Periodic Solutions of the Resonant Asymmetric pLaplacian Equation, Acta mathematica Sinica. English series (Print) , 21(5), 2005, pp. 1219-1228
In this paper, we give a Landesman.Lazer type theorem for periodic solutions of the asymmetric 1.dimensional p-Laplacian equation .(|x.|p.2x.).=.|x|p.2x++.|x|p.2x.+f(t,x) with periodic boundary value.
