Snyder and their representation with creation and annihilation operators
Juan M. Romero, Leonardo Ortíz
Inspired by the Schwinger's representation of angular momentum, we propose a representation of certain operators where we use the algebra of the annihilation and creation operators…

Aspects of the BTZ black hole interacting with fields
Leonardo Ortíz, Nora Bretón
We show that there is no superradiance for the Dirac field in the rotating BTZ black hole if the field vanishes at infinity. Then we outline the calculation of the expression for t…

On a Boltzmann equation for Compton scattering, from non relativistic electrons at low density
E. Cortés, M. Escobedo
A Boltzmann equation, used to describe the evolution of the density function of a gas of photons interacting by Compton scattering with electrons at low density and non relativisti…
