Abstract:By means of Mawhin’s the continuation theorem, a kind of even-order p-Laplacian equation with a deviation argument of the form ( )φp( )x(t)-cx(t-r) (n) (n)=f (x(t))x'(t)+g?è ??t,x( )t-τ( )t,|x|∞,|x'|∞ +e(t). is studied. Some new sufficient conditions for the existence of periodic solutions are obtained. It is notewor-thy that the growth degree with respect to the variable x in g(t,x) is allowed to be greater than p-1.
Keywords:periodic solution  p-Laplacian equation  even-order  Mawhin’s the continuation theo-rem  deviation argument
