> Scalable preconditioners for hybrid discontinuous Galerkin
> discretizations: an application to cardiac electrophysiology.
>
> Abstract:
> The drive to better understand complex phenomena like cardiac functions
> has led to mathematical models that are able to describe the multiscale
> structure and dynamics of the heart. The numerical simulation of these
> complex cardiac models is very challenging since it requires
> high-resolution space and time discretizations, as well as numerical tools
> that can handle natural discontinuities (for instance, disconnected cells).
>
> This talk will be divided into two parts: first, we derive a mathematical
> formulation of a cardiac microscopic model, starting from Maxwell's
> equations.  We will show how physiological discontinuities can be naturally
> included through a standard space discretization.
>
> In the second part, we build an ad-hoc non-overlapping domain
> decomposition preconditioner for the solution of the associated algebraic
> system. This preconditioner relies on the one introduced by Dryja et al.,
> but differs since it handles a global discontinuous solution across the
> domain.
> We conclude with a quick look at the theoretical convergence and at
> several numerical tests that show scalability and robustness of the
> proposed solver.
