By Ernst Hairer,Christian Lubich,Gerhard Wanner

This booklet covers numerical tools that safeguard houses of Hamiltonian platforms, reversible structures, differential equations on manifolds and issues of hugely oscillatory suggestions. It provides a


theory of symplectic and symmetric equipment, which come with numerous in particular designed integrators, in addition to discusses their building and sensible benefits. The long-time habit of the numerical suggestions is studied utilizing a backward errors research mixed with KAM theory.
