Abstract.
Let Ω be a bounded domain in \({\mathbb{R}}^{n}\) , we prove the singular Moser-Trudinger embedding: \(\mathop {\sup\limits_{\parallel u\parallel \leqslant 1\Omega } \int {\frac{{e^{\alpha |u|^{\frac{n} {{n - 1}}} } }}{{|x|^\beta }}} } < \infty\) if and only if \(\frac{\alpha}{{\alpha _n }} + \frac{\beta}{n} \leqslant 1\) where \(\alpha > 0,\beta \in [0,n),u \in W_0^{1,n} (\Omega )\) and \(\parallel u\parallel = \left({\int\limits_\Omega {|\nabla u|^n } } \right)^\frac{1}{n}\) . We will also study the corresponding critical exponent problem.
