On equal values of power sums of arithmetic progressions

A. Bazsó, D. Kreso, F. Luca +1

In this paper we consider the Diophantine equation \begin{align*}b^k +\left(a+b\right)^k &+ \cdots + \left(a\left(x-1\right) + b\right)^k=\\ &=d^l + \left(c+d\right)^l + \cdots + \…

Hamiltonian and Noether charges in first order gravity

Alejandro Corichi, Irais Rubalcava-Garcia, Tatjana Vukasinac

We consider gravity in four dimensions in the vielbein formulation, where the fundamental variables are a tetrad and a SO(3,1) connection . We start with the most general ac…

Multisymplectic effective General Boundary Field Theory

Mona Arjang, José A. Zapata

The transfer matrix in lattice field theory connects the covariant and the initial data frameworks; in spin foam models, it can be written as a composition of elementary cellular a…

A diagrammatic approach to Kronecker squares

Ernesto Vallejo

In this paper we apply a method of Robinson and Taulbee for computing Kronecker coefficients together with other ingredients and show that the multiplicity of each component in a K…

Inflationary Attractors and their Measures

Alejandro Corichi, David Sloan

Several recent misconceptions about the measure problem in inflation and the nature of inflationary attractors are addressed. We show that within the Hamiltonian system of flat Fri…

Multiplicative decomposition of arithmetic progressions in prime fields

M. Z. Garaev, S. V. Konyagin

We prove that there exists an absolute constant such that if an arithmetic progression $\cP$ modulo a prime number does not contain zero and has the cardinality less than…

Kloosterman sums in residue rings

J. Bourgain, M. Z. Garaev

In the present paper, we generalize some of the results on Kloosterman sums proven in \cite{BG} for prime moduli to general moduli. This requires to establish the corresponding add…

Loop quantum cosmology of k=1 FLRW: Effects of inverse volume corrections

Alejandro Corichi, Asieh Karami

We consider the k=1 Friedman-Lemaitre-Robertson-Walker (FLRW) model within loop quantum cosmology (LQC), from the perspective of the two available quantization prescriptions. We fo…

Chiral extensions of chiral polytopes

Gabe Cunningham, Daniel Pellicer

Given a chiral d-polytope K with regular facets, we describe a construction for a chiral (d + 1)-polytope P with facets isomorphic to K. Furthermore, P is finite whenever K is fini…

Towards state locality in quantum field theory: free fermions

Robert Oeckl

Hilbert spaces of states can be constructed in standard quantum field theory only for infinitely extended spacelike hypersurfaces, precluding a more local notion of state. In fact,…

Segal's spectral sequence in twisted equivariant K-theory for proper and discrete actions

Noe Barcenas, Jesus Espinoza, Bernardo Uribe +1

We use a spectral sequence developed by Graeme Segal in order to understand the twisted G-equivariant K-theory for proper and discrete actions. We show that the second page of this…

A local true Hamiltonian for the CGHS model in new variables

Saeed Rastgoo

Following our previous work, a complete classical solution of the CGHS model in Hamiltonian formulation in new variables is given. We preform a series of analyses and transformatio…

Quantum field theory on timelike hypersurfaces in Rindler space

Daniele Colosi, Dennis Rätzel

The general boundary formulation of quantum field theory is applied to a massive scalar field in two dimensional Rindler space. The field is quantized according to both the Schrödi…

Loop Quantum Cosmology

Ivan Agullo, Alejandro Corichi

This Chapter provides an up to date, pedagogical review of some of the most relevant advances in loop quantum cosmology. We review the quantization of homogeneous cosmological mode…
