Abstract: In this paper we give asymptotic estimates of the least energy solution $u_p$ of the functional

\begin{displaymath}J(u) =\int_\Omega \vert\nabla u\vert^2 \quad\hbox{constrained on the manifold }\int _\Omega \vert u\vert^{p+1}=1\end{displaymath}

as $p$ goes to infinity. Here $\Omega$ is a smooth bounded domain of $\mathbb{R}^2$. Among other results we give a positive answer to a question raised by Chen, Ni, and Zhou (2000) by showing that $\lim\limits_{p\rightarrow\infty}\vert\vert u_{p}\vert\vert _{\infty}=\sqrt e$.
