Sharp Trudinger-Moser inequalities with monomial weights

In this paper, we will study the Trudinger-Moser inequalities with the monomial weight x1A1...xNAN\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\left| x_{1}\right| ^{A_{1}}...\left| x_{N}\right| ^{A_{N}}$$\end{document} in RN\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \mathbb {R} ^{N}$$\end{document} with A1≥0,...,AN≥0\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$A_{1}\ge 0,..., A_{N}\ge 0$$\end{document}. Moreover, we investigate the Trudinger-Moser inequalities on both domains of finite and infinite volume. More importantly, we will exhibit the best constants for our results. In the particular case A1=⋯=\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$A_{1}=\cdots =$$\end{document}AN=0\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$A_{N}=0$$\end{document}, we recover many results about the Trudinger-Moser inequalities without weight established in the literature.
