A zoo of coisotropic embeddings
Rubén Izquierdo-López, Manuel de León, Luca Schiavone +1
The aim of this paper is to extend the coisotropic embedding theorem obtained by M. J. Gotay for pre-symplectic manifolds to more general geometric settings: cosymplectic, contact,…

The contact Eden bracket and the evolution of observables
V. M. Jiménez, M. De León
In this paper we discuss nonholonomic contact Lagrangian and Hamiltonian systems, that is, systems with a kind of dissipation that are also subject to nonholonomic constraints. We…

Invariant measures for contact Hamiltonian systems: symplectic sandwiches with contact bread
Alessandro Bravetti, Manuel de León, Juan Carlos Marrero +1
We prove that, under some natural conditions, Hamiltonian systems on a contact manifold can be split into a Reeb dynamics on an open subset of and a Liouville dynamics on a…
