| contents | In this paper, we use the method of blow-up analysis and capacity estimate to derive the singular Trudinger--Moser inequality involving $N$-Finsler--Laplacian and $L^{p}$ norm, precisely, for any $p>1$, $0\leqγ<γ_{1}:= \inf\limits_{u\in W^{1, N}_{0}(Ω)\backslash \{0\}}\frac{\int_ΩF^{N}(\nabla u)dx}{\| u\|_p^N}$ and $0\leqβ<N$, we have \begin{align} \sup_{u\in W_{0}^{1,N}(Ω),\;\int_ΩF^{N}(\nabla u)dx-γ\| u\|_p^N\leq1}\int_Ω\frac{e^{λ_{N}(1-\fracβ{N})\lvert u\rvert^{\frac{N}{N-1}}}}{F^{o}(x)^β}\;\mathrm{d}x<+\infty\notag, \end{align} where $λ_{N}=N^{\frac{N}{N-1}} κ_{N}^{\frac{1}{N-1}}$ and $κ_{N}$ is the volume of a unit Wulff ball in $\mathbb{R}^N$, moreover, extremal functions for the inequality are also obtained. When $F=\lvert\cdot\rvert$ and $p=N$, we can obtain the singular version of Tintarev type inequality by the obove inequality, namely, for any $0\leqα<α_{1}(Ω):=\inf\limits_{u\in W^{1, N}_{0}(Ω)\backslash \{0\}}\frac{\int_Ω|\nabla u|^Ndx}{\| u\|_N^N}$ and $0\leqβ<N$, it holds $$ \sup_{u\in W_{0}^{1,N}(Ω),\;\int_Ω\lvert\nabla u\rvert^{N}\;\mathrm{d}x-α\|u\|_{N}^{N}\leq1}\int_Ω\frac{e^{α_{N}(1-\fracβ{N})\lvert u\rvert^{\frac{N}{N-1}}}}{\lvert x\rvert^β}\;\mathrm{d}x<+\infty, $$ where $α_{N}:=N^{\frac{N}{N-1}}ω_{N}^{\frac{1}{N-1}}$ and $ ω_{N}$ is the volume of unit ball in $\mathbb{R}^{N}$. Our results extend many well-known Trudinger--Moser type inequalities to more general setting. |
