Derivation of nonlinear time-dependent macroscopic conductivity for an electropermeabilization model via homogenization
Tobias Gebäck, Ioanna Motschan-Armen, Irina Pettersson
We study a phenomenological electropermeabilization model in a periodic medium representing biological tissue. Starting from a cell-level model describing the electric potential an…

Euler-Maruyama approximations of the stochastic heat equation on the sphere
Annika Lang, Ioanna Motschan-Armen
The stochastic heat equation on the sphere driven by additive isotropic Wiener noise is approximated by a spectral method in space and forward and backward Euler-Maruyama schemes i…
