讨论了n维空间中一类具有转向点的奇异摄动二阶椭圆型方程的边值问题,通过分析相关方程产生共振的必要条件和充分条件,确定了椭圆方程Dirichlet问题解的渐近性态.
A class of singularly perturbed elliptic equation boundary value problems with a turning point in n-dimensional space is considered. Through considering the necessary and sufficient condition at resonance,the asymptotic behaviors of the solutions for the boundary value problem of elliptic equation are obtained.
