Title: Optimal embedding into the Lebesgue spaces for functions with gradient in the Morrey space


We will address the following natural question:
Given a function with support in the unit ball in dimension n, and with gradient in the Morrey space $M^{p,lambda}(B_1(0))$, which is the largest, or optimal, exponent $q$ such that $uin L^{q}(B_1(0))$?
We provide a counterexample for $q>lambda p/(lambda-p)$ and discuss several other candidates which did not seem to work. This is a joint work with Xavier Cabre.
