利用临界点理论研究p(x)-Laplace方程Dirichlet问题解的存在性。在具有局部超线性增长非线性项时,根据对称山路定理,得到方程多重解存在的充分条件。
By using critical point theory,the authors studied the existence of solutions for p(x)-Laplacian Dirichlet problems with local superlinear nonlinearity.Some sufficient conditions for the existence of multiplicity of solutions are obtained via the symmetric mountain pass theorem.
