摘要
在本文中,研究了方程div(｜u｜p-2u)+f(x,u)=0,x∈RN,N≥3的正整体解,其中f(x,u)在u=0未假定是正则的,且f(x,u)可以同时包含超线性,亚线性项和奇异项.
In this paper,we study the positive solutions div（｜↓△u｜p-2↓△u）＋f（x,u）=0,X∈R^N,N≥3where f（x,u） is not assumed to be regular near u = 0 and f（x,u） may be more general involving singular,sublinear and superlinear terms.
