sll_m_hamiltonian_splitting_base Module Reference

Description

Base class for Hamiltonian splittings.

Author

Katharina Kormann, IPP

Contains deferred function for strang splitting, lie splitting and lie splitting with oposite ordering of the split-steps. Moreover, composition methods based on lie and strang splitting are implemented (cf. Hairer, Lubich, Wanner, Geometric numeric integration.
