Well-posedness for a modified bidomain model describing bioelectric activity in damaged heart tissues
Micol Amar, Daniele Andreucci, Claudia Timofte
We prove the existence and the uniqueness of a solution for a modified bidomain model, describing the electrical behaviour of the cardiac tissue in pathological situations. The lea…
Homogenization of a modified bidomain model involving imperfect transmission
Micol Amar, Daniele Andreucci, Claudia Timofte
We study, by means of the periodic unfolding technique, the homogenization of a modified bidomain model, which describes the propagation of the action potential in the cardiac elec…
Well-posedness of two pseudo-parabolic problems for electrical conduction in heterogeneous media
Micol Amar, Daniele Andreucci, Roberto Gianni +1
We prove a well-posedness result for two pseudo-parabolic problems, which can be seen as two models for the same electrical conduction phenomenon in heterogeneous media, neglecting…
Concentration and homogenization in electrical conduction in heterogeneous media involving the Laplace-Beltrami operator
Micol Amar, Daniele Andreucci, Roberto Gianni +1
We study a concentration and homogenization problem modelling electrical conduction in a composite material. The novelty of the problem is due to the specific scaling of the physic…
Homogenization results for a coupled system of reaction-diffusion equations
G. Cardone, C. Perugia, C. Timofte
The macroscopic behavior of the solution of a coupled system of partial differential equations arising in the modeling of reaction-diffusion processes in periodic porous media is a…
