Remark on the exponential decay of the solutions of the damped wave equation
Giovanni Cimatti
A condition which guaranties the exponential decay of the solutions of the initial-boundary value problem for the damped wave equation is proved. A method for the effective computa…

A variational principle for the system of P.D.E. of porous metal bearings
Giovanni Cimatti
Porous metal bearings are widely used in small and micro devices. To compute the pressure one has to solve the Reynolds equation coupled with the Laplace equation. We show that it…
