Contact geometry allows to describe some thermodynamic and dissipative systems. In this paper we introduce a new geometric structure in order to describe time-dependent contact systems: cocontact manifolds. Within this setting we develop the Hamiltonian and Lagrangian formalisms, both in the regular and singular cases. In the singular case, we present a constraint algorithm aiming to find a submanifold where solutions exist. As a particular case we study contact systems with holonomic time…

Lagrangian-Hamiltonian formalism for time-dependent dissipative mechanical systems
In this paper we present a unified Lagrangian–Hamiltonian geometric formalism to describe time-dependent contact mechanical systems, based on the one first introduced by K. Kamimura and later
A variational derivation of the field equations of an action-dependent Einstein-Hilbert Lagrangian
For the past century Einstein’s theory of general relativity has constituted our most advanced understanding of gravitation and all of its associated phenomena. Nevertheless, there are still many


Constrained Lagrangian dissipative contact dynamics
We show that the contact dynamics obtained from the Herglotz variational principle can be described as a constrained nonholonomic or vakonomic ordinary Lagrangian system depending on a dissipative
On the geometry of discrete contact mechanics
A discrete Herglotz Principle and the corresponding discrete HerGlotz Equations for a discrete Lagrangian in the contact setting are introduced to develop convenient numerical integrators for contact Lagrangia systems that are conformally contact by construction.
Singular Lagrangians and precontact Hamiltonian systems
In this paper, we discuss the singular Lagrangian systems on the framework of contact geometry. These systems exhibit a dissipative behavior in contrast with the symplectic scenario. We develop a
Contact Hamiltonian and Lagrangian systems with nonholonomic constraints
In this article we develop a theory of contact systems with nonholonomic constraints. We obtain the dynamics from Herglotz's variational principle, by restricting the variations so that they satisfy
Contact Hamiltonian systems
In this paper, we study Hamiltonian systems on contact manifolds, which is an appropriate scenario to discuss dissipative systems. We show how the dissipative dynamics can be interpreted as a
Geometric Theory of Time-Dependent Singular Lagrangians
The geometry of jet bundles is used for obtaining a geometric approach to time-dependent Lagrangian systems, both in the regular and singular case. Generalized symmetries are introduced as being
Numerical integration in Celestial Mechanics: a case for contact geometry
This work starts an investigation of dynamical systems of interest in Celestial Mechanics from the point of view of contact geometry, and focuses on the (contact) Hamiltonisation of these models and on the construction of the corresponding geometric integrators.
