    • Lagrangian-Hamiltonian formalism for cocontact systems 

      Rivas, Xavier; Torres, Daniel (Journal of Geometric Mechanics, 2023)
      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 formalized by R. Skinner and ...

    • Multicontact formulation for non-conservative field theories 

      de León, Manuel; Gaset, Jordi; Muñoz-Lecanda, Miguel C.; Rivas, Xavier; Román-Roy, Narciso (Journal of Physics A: Mathematical and Theoretical, 2023)
      A new geometric structure inspired by multisymplectic and contact geometries, which we call multicontact structure, is developed to describe non-conservative classical field theories. Using the differential forms that ...

    • Time-dependent contact mechanics 

      de León, Manuel; Gaset, Jordi; Gràcia, Xavier; Muñoz-Lecanda, Miguel C.; Rivas, Xavier (Monatshefte fur Mathematik, 2023)
      Contact geometry allows us 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 ...
