Reparametrization Invariance and the Schrödinger Equation
V. I. Tkach, A. Pashnev, J. J. Rosales
In the present work we consider a time-dependent Schrödinger equation for systems invariant under the reparametrization of time. We develop the two-stage procedure of construction…

Massless and spinning particles as dynamics in one dimensional (super)diffeomorphism groups
A. Pashnev
It is shown that dynamics of D+2 elements of the (super)diffeomorphism group in one (1+1 for the super) dimension describes the D - dimensional (spinning) massless relativistic par…
