摘要: We deal with a large solution to the semilinear Poisson equation with double-power nonlinearity $\Delta u = u^p + \alpha u^q$ in a bounded smooth domain $D \subset \mathbb{R}^n$, where $p>1$, $-1<q<p$ and $\alpha \in \mathbb{R}$. We obtain the asymptotic behavior of a solution $u$ near the boundary $\partial D$ up to the third or higher term.
