摘要
利用Mawhin连续性定理,研究一类含偏差变元偶数阶p-Laplacian中立型微分方程(φp(x(t)-cx(t-δ))(n))(n)=f(x(t))x'(t)+g(t,x(t-τ(t,|x|∞,|x'|∞)))+e(t).获得其周期解存在性新的充分条件.值得注意的是g(t,x)关于x的增长级允许超过p-1.
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.
