Diameter and Laplace eigenvalue estimates for left-invariant metrics on compact Lie groups

Emilio A. Lauret

Let $G$ be a compact connected Lie group of dimension $m$ . Once a bi-invariant metric on $G$ is fixed, left-invariant metrics on $G$ are in correspondence with $m \times m$ positive…

Fuzzy Group Identification Problems

Federico Fioravanti, Fernando Tohmé

We present a fuzzy version of the Group Identification Problem ("Who is a J?") introduced by Kasher and Rubinstein (1997). We consider a class $N = {1, 2, \dots, n}$ of agents, eac…

Routh Reduction of Palatini Gravity in Vacuum

Santiago Capriotti

An interpretation of Einstein-Hilbert gravity equations as Lagrangian reduction of Palatini gravity is made. The main technique involved in this task consists in representing the e…

On the smallest Laplace eigenvalue for naturally reductive metrics on compact simple Lie groups

Emilio A. Lauret

Eldredge, Gordina and Saloff-Coste recently conjectured that, for a given compact connected Lie group $G$ , there is a positive real number $C$ such that $λ_1(G,g)\operatorname{diam…

Non-solvable Lie groups with negative Ricci curvature

Emilio A. Lauret, Cynthia E. Will

Until a couple of years ago, the only known examples of Lie groups admitting left-invariant metrics with negative Ricci curvature were either solvable or semisimple. We use a gener…

Recent results on the spectra of lens spaces

Emilio A. Lauret, Roberto J. Miatello, Juan Pablo Rossetti

In this paper we report on recent results by several authors, on the spectral theory of lens spaces and orbifolds and similar locally symmetric spaces of rank one. Most of these re…

Strong representation equivalence for compact symmetric spaces of real rank one

Emilio A. Lauret, Roberto J. Miatello

Let $G / K$ be a simply connected compact irreducible symmetric space of real rank one. For each $K$ -type $τ$ we compare the notions of $τ$ -representation equivalence with $τ$ -isospe…

Oversampling and undersampling in de Branges spaces arising from regular Schrödinger operators

Luis O. Silva, Julio H. Toloza, Alfredo Uribe

The classical results on oversampling and undersampling (or aliasing), of functions in Paley-Wiener spaces, are generalized to the case of functions in de Branges spaces arising fr…

Superrational types

Fernando Tohmé, Ignacio Viglizzo

We present a formal analysis of Douglas Hofstadter's concept of \emph{superrationality}. We start by defining superrationally justifiable actions, and study them in symmetric games…
