Central charges in regular mechanics
A. Cabo, J. L. Lucio M., V. Villanueva
We consider the algebra associated to a group of transformations which are symmetries of a regular mechanical system (i.e. system free of constraints). For time dependent coordinat…

About Black Holes Without Trapping Interior
Alejandro Cabo, Eloy Ayon
Physical arguments related with the existence of black hole solutions having a non trapping interior are discussed. Massive scalar fields interacting with gravity are considered. I…

On Scale Invariance and Anomalies in Quantum Mechanics
A. Cabo, J. L. Lucio, H. Mercado
We re-consider the quantum mechanics of scale invariant potentials in two dimensions. The breaking of scale invariance by quantum effects is analyzed by the explicit evaluation of…
