Fei Fang, Chao Ji

摘要:

本文首先研究了有界域和无界域$\mathbb{R}^2_{+}$上的锥Moser-Trudinger不等式及其最佳指数$α_2$。然后,利用锥Moser-Trudinger不等式,研究了非线性方程\begin{equation*} \left\{\begin{array}{ll} -Δ_{\mathbb{B}} u=f(x, u), &\mbox{in}\ x\in \mbox{int} (\mathbb{B}), \\ u= 0, &\mbox{on}\ \partial\mathbb{B}, \end{array} \right. \end{equation*}弱解的存在性,其中$Δ_{\mathbb{B}}$是在边界$x_1 =0$上具有全特征退化的Fuchsian型Laplace算子,非线性项$f$具有次临界指数增长性或临界指数增长性.

英文摘要:

In this article, we firstly study the cone Moser-Trudinger inequalities and their best exponents $α_2$ on both bounded and unbounded domains $\mathbb{R}^2_{+}$. Then, using the cone Moser-Trudinger inequalities, we study the existence of weak solutions to the nonlinear equation \begin{equation*} \left\{\begin{array}{ll} -Δ_{\mathbb{B}} u=f(x, u), &\mbox{in}\ x\in \mbox{int} (\mathbb{B}), \\ u= 0, &\mbox{on}\ \partial\mathbb{B}, \end{array} \right. \end{equation*} where $Δ_{\mathbb{B}}$ is Fuchsian type Laplace operator investigated with totally characteristic degeneracy on the boundary $x_1 =0$, and the nonlinearity $f$ has the subcritical exponential growth or the critical exponential growth.
