共振的半线性椭圆方程Dirichlet问题解的多重性

摘要

使用极小极大方法获得非线性非自治无界共振的半线 性椭圆方程Dirichlet问题解的多重性结果.%The multiplicty results are obtained for solutio ns of the Dirichlet problem for semilinear elliptic equations at resonance with unbounded and nonautonomous non-linearities by using the minimum maximum metho ds of critical point theory.
