A -contact Geometrical Approach to Pseudo-Gauge Transformation
Mykhailo Hontarenko, Javier de Lucas, Adam Maskalaniec
We propose a starting point to the geometric description for the pseudo-gauge ambiguity in relativistic hydrodynamics, showing that it corresponds to the freedom to redefine the th…

Marsden--Meyer--Weinstein reduction for -contact field theories
J. de Lucas, X. Rivas, S. Vilarino +1
This work devises a Marsden--Meyer--Weinstein -contact reduction. Our techniques are illustrated with several examples of mathematical and physical relevance. As a byproduct, we…

Foundations on k-contact geometry
Javier de Lucas, Xavier Rivas, Tomasz Sobczak
k-Contact geometry is a generalisation of contact geometry to analyse field theories. We develop an approach to k-contact geometry based on distributions that are distributionally…
