R^n上一类半线性椭圆方程解的存在唯一性和渐近性质

The Existence Uniqueness and Asymptotic Properties of a Class of Semilinear Elliptic Equations

用上下解方法和位势估计，研究Rn上具有次线性项加超线性项半线性椭圆方程给出了其有界正解的存在性、唯一性和渐近性质，其中为常数，参数．

In this paper , using sub and supsolution mecthods and potential estimations, westudy following semilinear elliptic equation on RN with sublinear and suplinear nonlinearities:RNThe existence uniqueness and asymptotic properties of bounded positive solution are givcn,where l is a constant O is a paramcter.
