Strong continuity of $langle Au,v rangle=int u^3 v dx$












0












$begingroup$


I am currently trying to figure out the following. If I consider the space $W^{1,p}_0$ is it possible to show that the operator given by
$$langle Au,v rangle=int u^3 v dx$$
is strongly (weak to strong) continuous for all $p$? We may assume we are on a bounded Lipschitz domain.
It is possible using the Sobolev embedding theorem but that will then restrict our choices of $p$ based on the dimension. I was told it is possible using the reverse dominated convergence theorem. Does anybody have any ideas?

    What is the "reverse dominated convergence theorem"? This operator is not defined if $p$ is too small (compared to the dimension).
