摘要
本文应用变分方法和截断技巧研究一类具有Neumann边值条件的Kirchhoff型方程.首先,通过方程对应的能量泛函及解的定义获得平凡解的等价条件;其次,对非线性项进行了奇假设证明了紧致性条件;最后,立足于空间分解来获得该问题存在无穷多解,并且它们对应的能量泛函收敛到零.
In this paper,we use a variational method and a truncation technique to study a class of Kirchhoff-type equations for Neumann boundary value problems.Firstly,the equivalence condition of trivial solutions is obtained by the definition of energy functionals and solutions corresponding to the equations;Secondly,the condition of compactness is proved by the odd hypothesis of the nonlinear term;Finally,the existence of infinite solutions is obtained based on spatial decomposition,and the corresponding energy functionals have zero gradation.
