Homogenization of degenerate parabolic Signorini problems with vanishing storage and oscillating surface fluxes
Hermann Douanla, Rodrigue Kenne Bogning, Erick Tetsadjio
We study the homogenization of a unilateral quasilinear parabolic problem in a periodically perforated medium. The model combines two degeneracies: the coefficient of the time deri…
Surface-to-Volume Homogenization of NonLinear Steklov Eigencouples with NonHomogeneous Orlicz Growth in Perforated Domains
Hermann Douanla, Hubert Nnang, Joel Fotso Tachago +1
We study normalized principal Steklov eigencouples on periodically perforated domains when both the bulk energy and the boundary normalization have general, possibly nonhomogeneous…
Bulk-surface spectral homogenization with indefinite mass in periodic perforated domains
Hermann DOUANLA
We study the homogenization of an elliptic eigenvalue problem in a periodically perforated domain, where the spectral parameter appears both in the equation, through a bulk density…
Deterministic homogenization of variational inequalities with unilateral constraints
Hermann Douanla, Cyrille Kenne
The article studies the reiterated homogenization of linear elliptic variational inequalities arising in problems with unilateral constrains. We assume that the coefficients of the…
Reiterated homogenization of hyperbolic-parabolic equations in domains with tiny holes
Hermann Douanla, Erick Tetsadjio
This article studies the homogenization of hyperbolic-parabolic equations in porous media with tiny holes. We assume that the holes are periodically distributed and that the coeffi…
Homogenization of reaction-diffusion equations in fractured porous media
Hermann Douanla, Jean Louis Woukeng
The paper deals with the homogenization of reaction-diffusion equations with large reaction terms in a multi-scale porous medium. We assume that the fractures and pores are equidis…
Homogenization of a nonlinear elliptic problem with large nonlinear potential
Hermann Douanla, Nils Svanstedt
Homogenization is studied for a nonlinear elliptic boundary-value problem with a large nonlinear potential. More specifically we are interested in the asymptotic behavior of a sequ…
Almost periodic homogenization of a generalized Ladyzhenskaya model for incompressible viscous flow
Hermann Douanla, Jean Louis Woukeng
The paper deals with the existence and almost periodic homogenization of some model of generalized Navier-Stokes equations. We first establish an existence result for non-stationar…
Two-scale convergence of elliptic spectral problems with indefinite density function in perforated domains
Hermann Yonta Douanla
Spectral asymptotics of linear periodic elliptic operators with indefinite (sign-changing) density function is investigated in perforated domains with the two-scale convergence met…
Homogenization of Steklov spectral problems with indefinite density function in perforated domains
Hermann Yonta Douanla
The asymptotic behavior of second order self-adjoint elliptic Steklov eigenvalue problems with periodic rapidly oscillating coefficients and with indefinite (sign-changing) density…
