Classical Klein-Gordon solutions, symplectic structures and isometry actions on AdS spacetimes
Max Dohse
We study classical, real Klein-Gordon theory on Lorentzian Anti de Sitter (AdS_{1,d}) spacetimes with spatial dimension d. We give a complete list of well defined and bounded Klein…
A positive formalism for quantum theory in the general boundary formulation
Robert Oeckl
We introduce a new "positive formalism" for encoding quantum theories in the general boundary formulation, somewhat analogous to the mixed state formalism of the standard formulati…
On the choice of time in the continuum limit of polymeric effective theories
Alejandro Corichi, Tatjana Vukasinac
In polymeric quantum theories, a natural question pertains to the so called continuum limit, corresponding to the limit where the `discreteness parameter' approaches zero. In p…
The lower algebraic -theory of virtually cyclic subgroups of the braid groups of the sphere and of
John Guaschi, Daniel Juan-Pineda, Silvia Millán-López
We study -theoretical aspects of the braid groups on strings of the -sphere, which by results of the second two authors, are known to satisfy the F…
Energy of test objects on black hole spacetimes: A brief review
Alejandro Corichi
In this paper, we review the issue of defining energy for test particles on a background stationary spacetime. We revisit the different notions of energy as defined by different ob…
On the Counting Function of Elliptic Carmichael Numbers
Florian Luca, Igor E. Shparlinski
We give an upper bound for the number elliptic Carmichael numbers that have recently been introduced by J. H. Silverman. We also discuss several possible ways for further…
Effective constrained polymeric theories and their continuum limit
Alejandro Corichi, Tatjana Vukasinac
The classical limit of polymer quantum theories yields a one parameter family of `effective' theories labeled by λ. Here we consider such families for constrained theories and pose…
Effective Dynamics in Bianchi Type II Loop Quantum Cosmology
Alejandro Corichi, Edison Montoya
We numerically investigate the solutions to the effective equations of the Bianchi II model within the "improved" Loop Quantum Cosmology (LQC) dynamics. The matter source is a mass…
Schrödinger-Feynman quantization and composition of observables in general boundary quantum field theory
Robert Oeckl
We show that the Feynman path integral together with the Schrödinger representation gives rise to a rigorous and functorial quantization scheme for linear and affine field theories…
