Time variation of the electron mass in the early universe and the Barrow-Magueijo model

Claudia G. Scóccola, Mercedes E. Mosquera, Susana J. Landau +1

We put limits on the time variation of the electron mass in the early universe using observational primordial abundances of D, He4 and Li7, recent data from the Cosmic Microwave Ba…

Non-perturbative scalar gauge-invariant metric fluctuations from the Ponce de Leon metric in the STM theory of gravity

Mariano Anabitarte, Mauricio Bellini

We study our non-perturbative formalism to describe scalar gauge-invariant metric fluctuations by extending the Ponce de Leon metric.

Optimal Non-Linear Models for Sparsity and Sampling

Akram Aldroubi, Carlos Cabrelli, Ursula Molter

Given a set of vectors (the data) in a Hilbert space H, we prove the existence of an optimal collection of subspaces minimizing the sum of the square of the distances between each…
