Metodi di simmetrizzazione nelle equazioni alle derivate parziali
A survey of the fundamental ideas which are the base of the socalled symmetrization method; a priori estimates in partial differential equations.
Equazioni ellittiche con termini di ordine inferiore e riordinamenti
We give a pointwise bound for the rearrangement of a solution of the Dirichlet problem for second order elliptic equations with lower order terms by means of the solution of a "symmetrized" problem.
Variational inequalities and rearrangements
We give comparison results for solutions of variational inequalities, related to general elliptic second order operators, involving solutions of symmetrized problems, using Schwarz spherical symmetrization.
