Combination and mean width rearrangements of solutions to elliptic equations in convex sets
Annales de l'I.H.P. Analyse non linéaire, Tome 32 (2015) no. 4, pp. 763-783.

We introduce a method to compare solutions of different equations in different domains. As a consequence, we define a new kind of rearrangement which applies to solution of fully nonlinear equations F(x,u,Du,D 2 u)=0, not necessarily in divergence form, in convex domains and we obtain Talenti's type results for this kind of rearrangement.
