摘要: 利用上下解方法讨论一类具有超临界增长非线性项的椭圆方程, 先证明Dirichlet问题在限制区域内解的存在性, 再结合新的变分原理, 证明限制区域内的局部解可延展到全区域.

关键词: 超临界增长, 变分法, 上下解, Carathéodory函数

Abstract: By using the method of upper and lower solutions, we discussed a class of elliptic equations with nonlinear terms of supercritical growth. We first proved the existence of solutions of the Dirichlet problem in the restricted region, and then proved that the local solutions in the restricted region could be extended to the whole region by combining a new  variational principle.

Key words: supercritical growth, variational method, upper and lower solutions, Carathéodory function
