一类超线性椭圆型方程组的正解
Positive Solutions of Some Superlinear Elliptic Systems
【摘要】 本文用blow-up方法和拓扑度理论讨论了单位球上一类超线性椭圆型方程组正径向解的存在性,给出存在正解的一些条件.
【Abstract】 <Ahstract>In this paper, the existence of positive solutions of some superlinear elliptic systems in {x∈Rn|N≥3, |x|<1} is considered. Using blow-up methods and Leray-Schauder’s fixed point theorems. we give some conditions under which tbe superlinear systems have positive radial solutions.
