A geometric approach to contact Hamiltonians and contact Hamilton–Jacobi theory

K Grabowska, J Grabowski - Journal of Physics A: Mathematical …, 2022 - iopscience.iop.org
We propose a novel approach to contact Hamiltonian mechanics which, in contrast to the
one dominating in the literature, serves also for non-trivial contact structures. In this …

Multicontact formulation for non-conservative field theories

M de León, J Gaset, MC Muñoz-Lecanda… - Journal of Physics A …, 2023 - iopscience.iop.org
A new geometric structure inspired by multisymplectic and contact geometries, which we call
multicontact structure, is developed to describe non-conservative classical field theories …

Contact dynamics: Legendrian and Lagrangian submanifolds

O Esen, M Lainz Valcázar, M de León, JC Marrero - Mathematics, 2021 - mdpi.com

the triple, namely symplectic diffeomorphisms, special symplectic manifolds, and Morse …

Reductions: precontact versus presymplectic

K Grabowska, J Grabowski - Annali di Matematica Pura ed Applicata (1923 …, 2023 - Springer
We show that contact reductions can be described in terms of symplectic reductions in the
traditional Marsden–Weinstein–Meyer as well as the constant rank picture. The point is that …

Contact geometric mechanics: the Tulczyjew triples

K Grabowska, J Grabowski - arXiv preprint arXiv:2209.03154, 2022 - arxiv.org
We propose a generalization of the classical Tulczyjew triple as a geometric tool in
Hamiltonian and Lagrangian formalisms which serves for contact manifolds. The role of the …

J de Lucas, X Rivas - Journal of Physics A: Mathematical and …, 2023 - iopscience.iop.org
A Lie system is a time-dependent system of differential equations describing the integral
curves of a time-dependent vector field that can be considered as a curve in a finite …
