A nonlinear interpolation result with application to the summability of minima of some integral functionals
We prove results asserting the (global) L s-summability of the minima of integral functionals, using the classical structural assumptions. A feature of the method is that it depends not so much on the minimization problem but rather on the “control from below” of the structural assumptions. Then the proof concerning the summability of the minima of integral functionals can be easily adapted in order to prove the summability of solutions of nonlinear elliptic equations (even when they are not Euler equations of functionals)
Elliptic problems with lower order terms having singular behaviour
We prove the existence of non negative distributional solutions to an elliptic problem with a lower order term which depends on the solution u in a singular way and on its gradient Du with quadratic growth
