Abstract: We study preconditioned iterative methods for the linear system arising in the numerical discretization of the Bidomain equations in electrocardiology. In each step of the time integration, a block two-by-two linear system is obtained and… read more here.

Abstract: Abstract A special two-by-two block matrix form arises in many important applications. Extending earlier results it is shown that parameter modified versions of a very efficient preconditioner does not improve its rate of convergence. This… read more here.
