A linear-time algorithm that avoids inverses and computes Jackknife (leave-one-out) products like convolutions or other operators in commutative semigroups [PDF]
Algorithms for Molecular Biology, 2020 Background Data about herpesvirus microRNA motifs on human circular RNAs suggested the following statistical question. Consider independent random counts, not necessarily identically distributed.

Commutative Topological Semigroups Embedded into Topological Abelian Groups
Axioms, 2020 In this paper, we give conditions under which a commutative topological semigroup can be embedded algebraically and topologically into a compact topological Abelian group.

Varieties of commutative semigroups [PDF]
Transactions of the American Mathematical Society, 1994 In this paper, we describe all equational theories of commutative semigroups in terms of certain well-quasi-orderings on the set of finite sequences of nonnegative integers. This description yields many old and new results on varieties of commutative semigroups.

Characterizing categorically closed commutative semigroups [PDF]
Journal of Algebra, 2021 Let C be a class of T1 topological semigroups which contains all zero-dimensional Hausdorff topological semigroups. A semigroup X is called C-closed if X is closed in each topological semigroup Y ∈ C containing X as a discrete subsemigroup; X is ...

Deviation bounds and concentration inequalities for quantum noises [PDF]
Quantum, 2022 We provide a stochastic interpretation of non-commutative Dirichlet forms in the context of quantum filtering. For stochastic processes motivated by quantum optics experiments, we derive an optimal finite time deviation bound expressed in terms of the ...

Epimorphisms, Dominions, and Various Classes of Saturated Semigroups
Journal of Mathematics, 2022 In this paper, we discussed some saturated classes of ℋ-commutative semigroups, left (right) regular semigroups, medial semigroups, and paramedial semigroups. The results of this paper significantly extend the long standing result about normal bands that

On determinability of idempotent medial commutative quasigroups by their endomorphism semigroups; pp. 81–87 [PDF]
Proceedings of the Estonian Academy of Sciences, 2011 We extend the result of P. Puusemp (Idempotents of the endomorphism semigroups of groups. Acta Comment. Univ. Tartuensis, 1975, 366, 76â104) about determinability of finite Abelian groups by their endomorphism semigroups to finite idempotent medial ...

Locality and Centrality: The Variety ZG [PDF]
Logical Methods in Computer Science, 2023 We study the variety ZG of monoids where the elements that belong to a group are central, i.e., commute with all other elements. We show that ZG is local, that is, the semidirect product ZG * D of ZG by definite semigroups is equal to LZG, the variety of

New models for some free algebras of small ranks
Karpatsʹkì Matematičnì Publìkacìï, 2023 Dimonoids, generalized digroups and doppelsemigroups are algebras defined on a set with two binary associative operations. The notion of a dimonoid was introduced by J.-L.

Right derivations on ordered semigroups [PDF]
Journal of Hyperstructures, 2019 Over the last few decades, several authors have investigated the relationship between the commutativity of ring R and the existence of certain specified derivations of R.
