Hoc approach to the dynamics of waves in excitable media

Abstract

This work is concerned with the High Order Compact HOC simulation of spiral waves in excitable media in general and study of spiral wave dynamics in particular An existing unconditionally stable O 226 8222 381 4 206 8221 240 8216 161 2 implicit HOC scheme for the two dimensional convection diffusion equations is reconstructed to discretize some of very well known models of pattern formation in excitable media notable amongst them are the Barkley and the FitzHugh Nagumo FHN models In the process it removes the...
