Existence of a sequence satisfying Cioranescu-Murat conditions in homogenization of Dirichlet problems in perforated domains
(Sapienza Università di Roma, 1996)
In a paper of 1982, D. Cioranescu and F. Murat considered the problem satisfied by the limit u of the sequence un solution of 0 −∆un = f in Ωn, un = 0 on ∂Ωn, where Ωn is a sequence of open sets which are contained in a ...

Relaxation of a control problem in the coefficients with a functional of quadratic growth in the gradient
(Society for Industrial and Applied Mathematics, 2008)
We study an optimal design problem consisting in mixing two anisotropic (electric or thermal) materials in order to minimize a functional depending on the gradient of the state. It is known that this type of problem has ...

The behavior of a beam fixed on small sets of one of its extremities
(AIMS, 2014-10)
In this paper we study the asymptotic behavior of the solution of an anisotropic, heterogeneous, linearized elasticity system in a thin cylinder (a beam). The beam is fixed (homogeneous Dirichlet boundary condition) on the ...

Asymptotic behaviour of linear Dirichlet parabolic problems with variable operators depending on time in varying domains
(Elsevier, 2005-06-01)
We study the asymptotic behaviour of the solutions of linear parabolic Dirichlet problems when the coefficients and the domains where the problems are posed vary simultaneously. In the limit problem it appear the H-limit ...
