摘要 本文研究了非线性项在无穷远处次线性增长的一类双调和方程解的存在性和多解性.应用抽象临界点定理,证明了此类双调和方程至少有三个弱解存在. In this article,we consider the existence of multiple solutions for a class of biharmonic equations,while the nonlinearity has a sublinear growth at infinity.By using an abstract critical point theorem,we prove the existence of at least three weak solutions to this kind of equations.
