研究了一类含Sobolev-Hardy临界指数与不定非线性项的奇异椭圆方程,通过Nehari流形和精确的能量估计,运用集中紧性原理与强极值原理得到了这类方程正解的存在性.
A class of singular elliptic equations with Sobolev-Hardy critical exponent and indefinite nonlinearity term is studied.With Nehari manifold and delicate energy estimates,the existence of positive solution is obtained by concentration-compactness principle and strong maximum principle.
