Homogenization of an indefinite spectral problem arising in population genetics
Srinivasan Aiyappan, Aditi Chattaraj, Irina Pettersson
We study an indefinite spectral problem for a second-order self-adjoint elliptic operator in an asymptotically thin cylinder. The operator coefficients and the spectral density fun…
Homogenization of Helmholtz equation in a periodic layer to study Faraday cage-like shielding effects
S Aiyappan, Georges Griso, Julia Orlik
The work is motivated by the Faraday cage effect. We consider the Helmholtz equation over a 3D-domain containing a thin heterogeneous interface of thickness . The layer has…
Homogenization of a nonlinear monotone problem in a locally periodic domain via unfolding method
S. Aiyappan, G. Cardone, C. Perugia +1
In this paper, the asymptotic behavior of the solutions of a monotone problem posed in a locally periodic oscillating domain is studied. Nonlinear monotone boundary conditions are…
Homogenization of a locally periodic oscillating boundary
Srinivasan Aiyappan, Klas Pettersson
This paper deals with the homogenization of a mixed boundary value problem for the Laplace operator in a domain with locally periodic oscillating boundary. The Neumann condition is…
