Abstract:
I will present some anisotropic Sobolev inequalities in $\mathbb{R}^{n}$ with a monomial weight in the general setting of rearrangement invariant spaces (e.g. $L^{p}$, Lorentz, Orlicz, etc...). The monomial weights are defined by $\begin{equation*} d\mu (x):=x^{A}dx=|x_{1}|^{A_{1}}\cdots |x_{n}|^{A_{n}}dx, \label{mu} \end{equation*}$ where $A=(A_{1},A_{2},\dots ,A_{n})$ is a vector in $\mathbb{R}^{n}$ with $% A_{i}\geq 0$ for $i=1,\dots ,n$. Some applications to study local boundedness of minimizers of a class of non uniformly elliptic integral functionals are also given.
