New directions for contact integrators (2106.10657v1)
Published 20 Jun 2021 in math.NA and cs.NA
Abstract: Contact integrators are a family of geometric numerical schemes which guarantee the conservation of the contact structure. In this work we review the construction of both the variational and Hamiltonian versions of these methods. We illustrate some of the advantages of geometric integration in the dissipative setting by focusing on models inspired by recent studies in celestial mechanics and cosmology.
