Hidden symmetries of the gravitational contact structure of the classical phase space of general relativistic test particle
Josef Janyska
The phase space of general relativistic test particle is defined as the 1-jet space of motions. A Lorentzian metric defines the canonical contact structure on the odd-dimensional p…
On the characterization of infinitesimal symmetries of the relativistic phase space
Josef Janyška, Raffaele Vitolo
The phase space of relativistic particle mechanics is defined as the 1st jet space of motions regarded as timelike 1-dimensional submanifolds of spacetime. A Lorentzian metric and…
Combinatorial differential geometry and ideal Bianchi-Ricci identities II - the torsion case
Josef Janyška, Martin Markl
This paper is a continuation of arXiv:0809.1158, dealing with a general, not-necessarily torsion-free, connection. It characterizes all possible systems of generators for vector-fi…
Combinatorial differential geometry and ideal Bianchi-Ricci identities
Josef Janyska, Martin Markl
We apply the graph complex method to vector fields depending naturally on a set of vector fields and a linear symmetric connection. We characterize all possible systems of generato…
