Alternating maps on Hatcher-Thurston graphs

Jesús Hernández Hernández

Let $S_{1}$ and $S_{2}$ be connected orientable surfaces of genus $g_{1}, g_{2} \geq 3$ , $n_{1}, n_{2} \geq 0$ punctures, and empty boundary. Let also $φ: \mathcal{HT}(S_{1}) \right…

A local and operational framework for the foundations of physics

Robert Oeckl

We discuss a novel framework for physical theories that is based on the principles of locality and operationalism. It generalizes and unifies previous frameworks, including the sta…

Poisson and near-symplectic structures on generalized wrinkled fibrations in dimension 6

Pablo Suárez-Serrato, Jonatán Torres Orozco, Ramón Vera

We show that generalized broken fibrations in arbitrary dimensions admit rank-2 Poisson structures compatible with the fibration structure. After extending the notion of wrinkled f…

Curving Flat Space-Time by Deformation Quantization?

Albert Much

We use a deformed differential structure to obtain a curved metric by a deformation quantization of the flat space-time. In particular, by setting the deformation parameters to be…

On classifying spaces for the family of virtually cyclic subgroups in mapping class groups

Daniel Juan-Pineda, Alejandra Trujillo-Negrete

We give a bound for the geometric dimension for the family of virtually cyclic groups in mapping class groups of a compact surface with punctures, possibly with nonempty boundary a…

Loop quantum cosmology of Bianchi IX: Inclusion of inverse triad corrections

Alejandro Corichi, Asieh Karami

We consider the loop quantization of the (diagonal) Bianchi type IX cosmological model. We explore different quantization prescriptions that extend the work of Wilson-Ewing and Sin…

Stable finiteness properties of infinite discrete groups

Noé Bárcenas, Dieter Degrijse, Irakli Patchkoria

Let $G$ be an infinite discrete group. A classifying space for proper actions of $G$ is a proper $G$ -CW-complex $X$ such that the fixed point sets $X^{H}$ are contractible for all fi…

Actions, topological terms and boundaries in first order gravity: A review

Alejandro Corichi, Irais Rubalcava-Garcia, Tatjana Vukasinac

In this review we consider first order gravity in four dimensions. In particular, we focus our attention in formulations where the fundamental variables are a tetrad $e_{a}^{I}$ and a…

The Ellis semigroup of a nonautonomous discrete dynamical system

S. García-Ferreira, M. Sanchis

We introduce the {\it Ellis semigroup} of a nonautonomous discrete dynamical system $(X, f_{1, \infty})$ when $X$ is a metric compact space. The underlying set of this semigroup is t…

Diophantine triples with values in $k$ -generalized Fibonacci sequences

Clemens Fuchs, Christoph Hutle, Florian Luca +1

We show that if $k \geq 2$ is an integer and $(F_{n}^{(k)})_{n \geq 0}$ is the sequence of $k$ -generalized Fibonacci numbers, then there are only finitely many triples of positive intege…
