WebJul 15, 2024 · The stability of such methods has remained an ensuing difficult open problem. In this work we consider a fourth order operator splitting discretization for the Allen-Cahn equation which is a prototypical high order splitting method with negative time-stepping, i.e. backward in time integration for the linear parabolic part. WebMar 1, 2024 · These are low-order methods (first and second order, respectively). Symmetrized methods, whereby one splitting method is applied in tandem with its adjoint, are a popular approach for achieving higher-order splitting methods; the Strang–Marchuk splitting method can be derived from the Lie–Trotter/Godunov method in this fashion [4]. …
