Title: Asymptotic behavior of ground state solution for Henon type systems Authors: Ying Wang (Jiangxi Normal Univ., Nanchang, China) Jianfu Yang (Jiangxi Normal Univ., Nanchang, China) Abstract: In this article, we investigate the asymptotic behavior of positive ground state solutions, as $\alpha\to\infty$, for the following Henon type system $$ -\Delta u=\frac{2p}{p+q}|x|^\alpha u^{p-1}v^q,\quad -\Delta v=\frac{2q}{p+q}|x|^\alpha u^pv^{q-1},\quad \hbox{in } B_1(0) $$ with zero boundary condition, where $B_1(0)\subset\mathbb{R}^N$ ($N\geq3$) is the unit ball centered at the origin, $p,q>1$, $p+q<2^*=2N/(N-2)$. We show that both components of the ground solution pair $(u, v)$ concentrate on the same point on the boundary $\partial B_1(0)$ as $\alpha\to\infty$. Submitted July 14, 2010.
