Null Controllability for a simplified degenerating reaction-diffusion in cardiology
Resumen
We analyze the null controllability of a nonlinear reaction-diffusion system approximating a parabolic-elliptic system modeling electrical activity in the heart. The uniform, with respect to the degenerating parameter, null controllability of the approximating system by means of a single control is shown. The proof is based on the combination of Carlemans estimates and weighted energy inequalities.
