A geometric approach to the generalized Noether theorem
Alessandro Bravetti, Angel Garcia-Chung
We provide a geometric extension of the generalized Noether theorem for scaling symmetries recently presented in \cite{zhang2020generalized}. Our version of the generalized Noether…
Squeeze operator: a classical view
Angel Garcia-Chung
In this paper we show the relation between , the Lie algebra of the symplectic group, and the elements of the symplectic group . We use this rel…
Dirac's formalism for time-dependent Hamiltonian systems in the extended phase space
Angel Garcia-Chung, Daniel Gutiérrez Ruiz, J. David Vergara
The Dirac's formalism for constrained systems is applied to the analysis of time-dependent Hamiltonians in the extended phase space. We show that the Lewis invariant is a reparamet…
Exact Baker-Campbell-Hausdorff formula for the contact Heisenberg algebra
Alessandro Bravetti, Angel Garcia-Chung, Diego Tapias
In this work we introduce the contact Heisenberg algebra which is the restriction of the Jacobi algebra on contact manifolds to the linear and constant functions. We give the exact…
