Improving the stability and efficiency of high-order operator-splitting methods
Siqi Wei, Victoria Guenter, Raymond J. Spiteri
Operator-splitting methods are widely used to solve differential equations, especially those that arise from multi-scale or multi-physics models, because a monolithic (single-metho…

A pair of Second-order complex-valued, N-split operator-splitting methods
Raymond J. Spiteri, Siqi Wei
The use of operator-splitting methods to solve differential equations is widespread, but the methods are generally only defined for a given number of operators, most commonly two.…
