Algebraic Operator Splittings+
Summary
The main motivation behind operator splitting methods is the simpler and faster implicit treatment of individual components in comparison to the entire operator which is typically difficult to invert. We develop an algebraic framework for operator splitting preconditioners for general invertible sparse matrices. In particular, it generalizes ADI and ILU methods to multiple factors and more general factor form.
