Evolutionary equations and constraints: Maxwell equations
Florio M. Ciaglia, Fabio Di Cosmo, Giuseppe Marmo +1
By fixing a reference frame in spacetime, it is possible to split the Euler-Lagrange equations associated with a degenerate Lagrangian into purely evolutionary equations and constr…
Descriptions of Relativistic Dynamics with World Line Condition
Florio M. Ciaglia, Fabio Di Cosmo, Alberto Ibort +1
In this paper a generalized form of relativistic dynamics is presented: A realization of the Poincaré algebra is provided in terms of vector fields on the tangent bundle of a simul…
Nonlinear Dynamics from Linear Quantum Evolutions
Florio M. Ciaglia, Fabio Di Cosmo, Armando Figueroa +5
Linear dynamics restricted to invariant submanifolds generally gives rise to nonlinear dynamics. Submanifolds in the quantum framework may emerge for several reasons: one could be…
Groupoids and Coherent states
Fabio Di Cosmo, Alberto Ibort, Giuseppe Marmo
Schwinger's algebra of selective measurements has a natural interpretation in terms of groupoids. This approach is pushed forward in this paper to show that the theory of coherent…
