Operator splitting for exploiting linear-rate closure in solving infinite ODE hierarchies
Linear-rate ODE hierarchies can be solved in-window exactly—no boundary cap—by integrating a low-dimensional coefficient ODE and composing generating functions; Strang splitting extends the trick to partially linear-rate models like Schlögl and predator-prey.
