Comparison results between minimal barriers and viscosity solutions for geometric evolutions
Comparison results for a class of variational inequalities.
In this paper we study a variational inequality related to a linear differential operator of elliptic type. We give a pointwise bound for the rearrangement of the solution u, and an estimate for the L2-norm of the gradient of u.

Comparison theorems for infinite systems of parabolic functional-differential equations
The paper deals with a weakly coupled system of functional-differential equations , i ∈ S, where (t,x) = (t,x₁,...,xₙ) ∈ (0,a) × G, and S is an arbitrary set of indices. Initial boundary conditions are considered and the following questions are discussed: estimates of solutions, criteria of uniqueness, continuous dependence of solutions on given functions. The right hand sides of the equations satisfy nonlinear estimates of the Perron type with respect to the unknown functions. The results are...

Comparison theorems for some quasilinear degenerate elliptic operators and applications to symmetry and monotonicity results
Comparison theorems for temperatures in noncylindrical domains
In questa Nota gli autori presentano alcuni risultati riguardanti il comportamento alla frontiera di domini non cilindrici delle soluzioni positive dell'equazione del calore. Una conseguenza è che due soluzioni positive qualunque, che si annullano su una parte della frontiera laterale, tendono a zero con lo stesso ordine.

Compensated compactness and time-periodic solutions to non-autonomous quasilinear telegraph equations
In the present paper, the existence of a weak time-periodic solution to the nonlinear telegraph equation with the Dirichlet boundary conditions is proved. No “smallness” assumptions are made concerning the function . The main idea of the proof relies on the compensated compactness theory.
