Abstract:

Splitting schemes constitute an effective class of time integrators and are widely used for both ODEs and PDEs. The general error analysis of such methods have often been conducted in a fairly classical ODE setting, including Taylor expansions and nonstiff order conditions, which is not directly applicable in a PDE context. In this talk we will survey our recent work, including the derivation of high order schemes and a convergence analysis for splitting methods applied to a large class of semilinear evolution equations, including Caginalp's phase field model and the Gray-Scott pattern formation problem.
