Bloch wave homogenization and spectral asymptotic analysis
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 1998-02)
We consider a second-order elliptic equation in a bounded periodic heterogeneous medium and study the asymptotic behavior of its spectrum, as the structure period goes to zero. We use a new method of Bloch wave homogenization ...
Positive solutions for systems of quasilinear equations with non-homogeneous operators and weights
(Walter de Gruyter, 2020)
In this paper we deal with positive radially symmetric solutions for a boundary value problem containing a strongly nonlinear operator. The proof of existence of positive solutions that we give uses the blow-up method as ...
Vector p-laplacian like operators, pseudo-eigenvalues, and bifurcation
(2007)
Boundary value problems for systems of ordinary differential equations are studied. These systems involve asymptotically homogeneous operators. Leray-Schauder indices are calculated for these operators and the concept of ...
Asymptotics for eigenvalues of the Laplacian in higher dimensional periodically perforated domains
(2010)
This paper considers the periodic spectral problem associated with the Laplace operator written in RN (N = 3, 4, 5)
periodically perforated by balls, and with homogeneous Dirichlet condition on the boundary of holes. We ...

Spectral asymptotics of the Helmholtz model in fluid-solid structures
(JOHN WILEY, 1999-11-30)
A model representing the vibrations of a coupled fluid-solid structure is considered. This structure consists of a tube bundle immersed in a slightly compressible fluid. Assuming periodic distribution of tubes, this article ...
Reduction of infinite dimensional systems to finite dimensions: Compact convergence approach
(2013-07-10)
We consider parameter dependent semilinear evolution problems for which, at the limit value of the parameter, the problem is finite dimensional. We introduce an abstract functional analytic framework that applies to many ...
