Abstract
We consider the class of implicit-explicit (IMEX) general linear methods (GLMs) to construct methods where the explicit part has strong stability preserving (SSP) property, while the implicit part of the method has inherent Runge-Kutta stability (IRKS) property, and it is A-, or L-stable. We will also investigate the absolute stability of these methods when the implicit and explicit parts interact with each other. In particular, we will monitor the size of the region of absolute stability of the IMEX scheme, assuming that the implicit part of the method is A(alpha)-stable for alpha is an element of [0, pi/2]. Finally we furnish examples of SSP IMEX GLMs up to the order p = 4 and stage order q = p with optimal SSP coefficients.
