Connectedness like properties on the hyperspace of convergent sequences
S. Garcia-Ferreira, R. Rojas-Hernandez
This paper is a continuation of the work done in \cite{sal-yas} and \cite{may-pat-rob}. We deal with the Vietoris hyperspace of all nontrivial convergent sequences $\mathcal{S}_c(X…
Some results on deformations of sections of vector bundles
Abel Castorena, Gian Pietro Pirola
Let be a vector bundle on a smooth complex projective variety . We study the family of sections where is a family of topological…
Topological rigidity of higher graph manifolds
Noé Bárcenas, Daniel Juan-Pineda, Pablo Suárez-Serrato
In this short note we prove the Borel conjecture for a family of aspherical manifolds that includes higher graph manifolds.
Sylvester's Theorem and the Non-integrality of a certain Binomial Sum
Daniel López-Aguayo, Florian Luca
In this note, we show that is not an integer for any positive integer and and for . This giv…
Families of continuous retractions and function spaces
S. Garcia-Ferreira, R. Rojas-Hernandez
In this article, we mainly study certain families of continuous retractions (-skeletons) having certain rich properties. By using monotonically retractable spaces we solve a que…
Covariance in models of loop quantum gravity: Spherical symmetry
Martin Bojowald, Suddhasattwa Brahma, Juan D. Reyes
Spherically symmetric models of loop quantum gravity have been studied recently by different methods that aim to deal with structure functions in the usual constraint algebra of gr…
The gravitational Hamiltonian, first order action, Poincaré charges and surface terms
Alejandro Corichi, Juan D. Reyes
We consider the issue of attaining a consistent Hamiltonian formulation, after a 3+1 splitting, of a well defined action principle for asymptotically flat gravity. More precisely,…
Energy in first order 2+1 gravity
Alejandro Corichi, Irais Rubalcava-Garcia
We consider =0 three dimensional gravity with asymptotically flat boundary conditions. This system was studied by Ashtekar and Varadarajan within the second order formalism -wit…
Loop quantum cosmology of Bianchi IX: Effective dynamics
Alejandro Corichi, Edison Montoya
We study numerically the solutions to the effective equations of Bianchi IX spacetimes within Loop Quantum Cosmology. We consider Bianchi IX models with and without inverse triad c…
Complex structures for an S-matrix of Klein-Gordon theory on AdS spacetimes
Max Dohse, Robert Oeckl
While the standard construction of the S-matrix fails on Anti-de Sitter (AdS) spacetime, a generalized S-matrix makes sense, based on the hypercylinder geometry induced by the boun…
