    • 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 ...

    • On k-polycosymplectic Marsden–Weinstein reductions 

      Lucas, Javier de; Rivas, Xavier; Vilariño, Silvia; Zawora, Bartosz M. (Journal of Geometry and Physics, 2023)
      We review and slightly improve the known k-polysymplectic Marsden–Weinstein reduction theory by removing some technical conditions on k-polysymplectic momentum maps by developing a theory of affine Lie group actions for ...
