Determination of Cavities in Nonlinear Parabolic Systems Arising from Electrophysiology

In this paper, starting from the well-known time monodomain model used in cardiac electrophysiology, we extend some of the results known in the existing literature, which addresses the identification of perfectly insulating regions (cavities) through partial boundary measurements. We show that, beyond the models typically employed in cardiac electrophysiology, unique recovery results for cavities can be established in more general contexts.
