The Protasov-Zelenyuk topology and ideal convergence

Lydia Außenhofer, Dikran Dikranjan, Anna Giordano Bruno

The so-called $T$ -sequences $u$ in a group $G$ , and the related finest Hausdorff group topology $T_{u}$ on $G$ that makes $u$ a null sequence, were introduced…

Nested ideals and topologically $u_{I}$ -torsion elements of the circle group

R. Di santo, D. Dikranjan, A. Giordano Bruno +1

Let $u = (u_{n})_{n \in N}$ be a sequence in $N_{+}$ with $u_{0} = 1$ and $u_{n} ∣ u_{n + 1}$ for every $n \in N$ , and let $b_{n} := u_{n + 1} / u_{n}$ for every $n\in\mathbb…

Exploring Ultralight Dark Matter Self-Coupling via the Gravitational Wave Background

Pratick Sarkar

Supermassive black hole (SMBH) binary mergers are a primary source of the stochastic gravitational wave background (SGWB) in the nanohertz band, now being actively probed by pulsar…

Ore localization of amenable monoid actions and applications towards entropy $-$ addition formulas and the bridge theorem

Dikran Dikranjan, Anna Giordano Bruno, Simone Virili

For a left action $S ↷ λ X$ of a cancellative right amenable monoid $S$ on a discrete Abelian group $X$ , we construct its Ore localization $G\overset{λ^*}{\cu…

Weakly weighted generalised quasi-metric spaces and semilattices

Ilaria Castellano, Anna Giordano Bruno, Nicolò Zava

Motivated by recent applications to entropy theory in dynamical systems, we generalise notions introduced by Matthews and define weakly weighted and componentwisely weakly weighted…

The addition theorem for locally monotileable monoid actions

Dikran Dikranjan, Antongiulio Fornasiero, Anna Giordano Bruno +1

We prove an instance of the so-called Addition Theorem for the algebraic entropy of actions of cancellative right amenable monoids $S$ on discrete abelian groups $A$ by endomorphis…
