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…
Homogenization of a Wilson-Cowan model for neural fields
Nils Svanstedt, Jean Louis Woukeng
Homogenization of Wilson-Cowan type of nonlocal neural field models is investigated. Motivated by the presence of a convolution terms in this type of models, we first prove some ge…
G-Convergence of Dirac Operators
Hasan Almanasreh, Nils Svanstedt
We consider the linear Dirac operator with a (-1)-homogeneous locally periodic potential that varies with respect to a small parameter. Using the notation of G-convergence for posi…
Stabilized Finite Element Method for the Radial Dirac Equation
Hasan Almanasreh, Sten Salomonson, Nils Svanstedt
A challenging difficulty in solving the radial Dirac eigenvalue problem numerically is the presence of spurious (unphysical) eigenvalues among the correct ones that are neither rel…
Periodic Homogenization of strongly nonlinear reaction-diffusion equations with large reaction terms
Nils Svanstedt, Jean Louis Woukeng
We study in this paper the periodic homogenization problem related to a strongly nonlinear reaction-diffusion equation. Owing to the large reaction term, the homogenized equation h…
Existence and homogenization of the Rayleigh-Bénard problem
Björn Birnir, Nils Svanstedt
The Navier-Stokes equation driven by heat conduction is studied. As a prototype we consider Rayleigh-Bénard convection, in the Boussinesq approximation. Under a large aspect ratio…
