Monoid Varieties with Extreme Properties

, 2018
Finite monoids that generate monoid varieties with uncountably many subvarieties seem rare, and, surprisingly, no finite monoid is known to generate a monoid variety with countably infinitely many subvarieties.

Characterizing Topologically Dense Injective Acts and Their Monoid Connections

Journal of Mathematics
In this paper, we explore the concept of topologically dense injectivity of monoid acts. It is shown that topologically dense injective acts constitute a class strictly larger than the class of ordinary injective ones.

Topological Structures Induced by General Fuzzy Automata Based on Lattice-ordered Monoid

پژوهش‌های ریاضی, 2021
The fundamental role of algebraic properties in the development of the basics of computer science has led researchers to study the concepts of fuzzy automaton separatedness, connectedness, and reversibility on a large scale.In this paper, the general ...

The asymptotic Mahler measure of Gaussian periods

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We construct a sequence of cyclotomic integers (Gaussian periods) of particularly small Mahler measure/height. We study the asymptotics of their Mahler measure as a function of their conductor, to find that the growth rate is the (multivariate) Mahler measure of a family of log Calabi–Yau varieties of increasing dimension.

Ideals of Lattice Ordered Monoid

, 2017
In this project the notion of an ideal of a lattice ordered monoid A is introduced. The notion of congruence relations on a lattice ordered monoid (l-monoid) A is also introduced and its relation with ideals of A is investigated.

Maximal subgroups of free projection‐ and idempotent‐generated semigroups with applications to partition monoids

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract This paper investigates the maximal subgroups of a free projection‐generated regular ∗$*$‐semigroup PG(P)${{\textsf {PG}}}(P)$ over a projection algebra P$P$, and their relationship to the maximal subgroups of the free idempotent‐generated semigroup IG(E)${{\textsf {IG}}}(E)$ over the corresponding biordered set E=E(P)$E = {{\textsf {E}}}(P)$.

The Order of Generalized Hypersubstitutions of Type τ=(2)

International Journal of Mathematics and Mathematical Sciences, 2008
The order of hypersubstitutions, all idempotent elements on the monoid of all hypersubstitutions of type τ=(2) were studied by K. Denecke and Sh. L. Wismath and all idempotent elements on the monoid of all hypersubstitutions of type τ=(2,2) were studied ...

Computing Bonds Between Formal Contexts

Mathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 11661-11677, 30 July 2026.
ABSTRACT The notion of bond was introduced as a technique to aggregate information from multiple datasets without modifying the information already present in each of the datasets. This notion has been extended to several fuzzy frameworks, including the residuated lattice setting, which we also consider in this paper.

Intersection Graphs of Monoids in a Graphical Homotopy Framework via Path Spaces and Homogeneous Structures: Some Applications to Graphical Comprehensive Monoids

Mathematics
In this work, we construct a homotopy theory for a class of intersection graphs arising from topological monoids. We introduce the M-intersection graph of a τe-monoid, where the vertices correspond to proper τe-submonoids and adjacency is defined by ...

Oppenheim–Schur inequalities for causal products

Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We establish a class of Oppenheim–Schur‐type inequalities for the convolutional Jury product of positive semidefinite matrices. These results extend the classical Schur and Oppenheim inequalities associated with the Hadamard product to a causal convolutional setting.
