A generalized monoid of infinite words: asymptotic prefix-suffix quotients and algebraic structure
A. Alvarez Cruz, E. A. Alvarez Gutierrez
A generalized monoid of words tilde{Sigma}* is constructed as the quotient of moderate nets of finite words by an asymptotic equivalence relation based on a bidirectional prefix-su…

Multiplicative Colombeau algebras and the Nyman--Beurling criterion for the Riemann hypothesis
Amaury Alvarez Cruz, Esteban A Alvarez Gutierrez
This paper establishes an equivalence between the Riemann hypothesis and the association, together with uniform -boundedness, of a moderate net in a Colombeau-type algebra bui…

Quantization of edge currents along magnetic interfaces: A K-theory approach
Giuseppe De Nittis, Esteban Gutiérrez
The purpose of this paper is to investigate the propagation of topological currents along magnetic interfaces (also known as magnetic walls) of a two-dimensional material. We consi…
