一类具有耦合项的Kirchhoff型双调和方程组正解的存在性和多解性

摘要

In this paper,we study a coupled fourth-order system of Kirchhoff type.Under appropriate hypotheses of V_(i)(x)for i=1,2,f and g,we obtained two main existence theorems of weak solutions for the problem by variational methods.Some recent results are extended.
