Existence of periodic solutions for p-Laplacian equation under the frame of Fu $$ \overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\smile}$}}{c} $$ik spectrum.

In this paper, under the frame of Fu $$ \overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\smile}$}}{c} $$ik spectrum, we study the existence of periodic solutions for p-Laplacian equation by asymptotic behaviors of potential function, improve some results to some extent. [ABSTRACT FROM AUTHOR]
