On the centralizer and normalizer groups of odometers and Toeplitz subshifts

Jaime Gómez, Samuel Petite

For residually finite groups, we study the automorphism and normalizer groups of odometers and their symbolic extensions: Toeplitz subshifts. In relation to orbit equivalence theor…

Constructing Toeplitz arrays via cut and project schemes

María Isabel Cortez, Jamal Drewlo, Jaime Gómez +1

We show a one-to-one correspondence between Toeplitz arrays over residually finite topological groups and model sets obtained via specific cut and project schemes, built from the o…

Sequence entropy and independence in free and minimal actions

Jaime Gómez, Irma León-Torres, Víctor Muñoz-López

For every countable infinite group that admits as a homomorphic image, we show that for each , there exists a minimal action whose topological sequence…

Multisoliton solutions and blow up for the -critical Hartree equation

Jaime Gómez, Tobias Schmid, Yutong Wu

We construct multisoliton solutions for the -critical Hartree equation with trajectories asymptotically obeying a many-body law for an inverse square potential. Precisely, we…

Uniform stability of concentration inequalities and applications

Jaime Gómez, David Kalaj, Petar Melentijević +1

We prove a sharp quantitative version of recent Faber-Krahn inequalities for the continuous Wavelet transforms associated to a certain family of Cauchy wavelet windows . Our result…

Almost 1-1 extensions of Furstenberg-Weiss type and test for amenability

María Isabel Cortez, Jaime Gómez

Let be an infinite residually finite group. We show that for every minimal equicontinuous Cantor system with a free orbit, and for every minimal extension of $(…

Almost automorphic systems have invariant measures

María Isabel Cortez, Jaime Gómez

Let be a non-amenable countable group. We show that every almost automorphic -action on a compact Hausdorff space, with a maximal equicontinuous factor whose phase space is…

Topo-isomorphisms of irregular Toeplitz subshifts for residually finite groups

Jaime Gómez

For each countable residually finite group , we present examples of irregular Toeplitz subshifts in that are topo-isomorphic extensions of its maximal equicontinuous…
