Jul 3 at 19:42 comment added Math604 Okay, thanks again. I am not familiar at all with these other spaces.
Jul 3 at 19:40 comment added Piero D'Ancona Of course, the $L^{q,2}$ norm is controlled by the $L^2$ norm of $\partial u$. This is a Sobolev embedding with values in Lorentz spaces

Jul 3 at 19:38 comment added Math604 Now i remember how..thanks.
Jul 3 at 19:37 comment added Math604 Thank you very much for your answer. Are you able to control this norm on the right by the Dirichlet energy also or ? Also, i am trying to ''accept'' your answer but i seem to have forgotten how (eventually i will figure it out).
