Graded Poisson and Graded Dirac structures

Manuel de León, Rubén Izquierdo-López

There have been several attempts in recent years to extend the notions of symplectic and Poisson structures in order to create a suitable geometrical framework for classical field…

Symmetries, conservation and dissipation in time-dependent contact systems

Jordi Gaset, Asier López-Gordón, Xavier Rivas

In contact Hamiltonian systems, the so-called dissipated quantities are akin to conserved quantities in classical Hamiltonian systems. In this paper, we prove a Noether's theorem f…

The Herglotz variational principle for dissipative field theories

Jordi Gaset, Manuel Lainz, Arnau Mas +1

In the recent years, with the incorporation of contact geometry, there has been a renewed interest in the study of dissipative or non-conservative systems in physics and other area…

Nonautonomous k-contact field theories

Xavier Rivas

This paper provides a new geometric framework to describe non-conservative field theories with explicit dependence on the space-time coordinates by combining the k-cosymplectic and…

Multicontact formulation for non-conservative field theories

Manuel de León, Jordi Gaset, Miguel Carlos Muñoz-Lecanda +2

A new geometric framework is developed to describe non-conservative classical field theories, which is based on multisymplectic and contact geometries. Assuming certain additional…

Hamilton-Jacobi theory and integrability for autonomous and non-autonomous contact systems

Manuel de León, Manuel Lainz, Asier López-Gordón +1

In this paper, we study the integrability of contact Hamiltonian systems, both time-dependent and independent. In order to do so, we construct a Hamilton--Jacobi theory for these s…
