Splitting in Action Network

Different splitting methods have played important roles in the numerical solution of differential equations. Since the pioneering work on ADI and exponential splitting formulae, many new concepts and strategies have been developed and utilized. Splitting methods associated with finite differences, finite elements, or adaptations have been used widely and have been shown to have powerful capabilities in solving different differential equation problems in various applications.
