On semisimple commutative semigroups [PDF]

open access: yesTransactions of the American Mathematical Society, 1975
This paper presents an application of radical theory to the structure of commutative semigroups via their semilattice decomposition. Maximal group congruences and semisimplicity are characterized for certain classes of commutative semigroups and

The rank of a commutative semigroup [PDF]

open access: yesMathematica Bohemica, 2009
summary:The concept of rank of a commutative cancellative semigroup is extended to all commutative semigroups $S$ by defining $\mathop{\rm rank}S$ as the supremum of cardinalities of finite independent subsets of $S$. Representing such a semigroup $S$ as

A linear-time algorithm that avoids inverses and computes Jackknife (leave-one-out) products like convolutions or other operators in commutative semigroups [PDF]

open access: yesAlgorithms 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.

Unification in Commutative Semigroups

open access: yesJournal of Algebra, 1998
Unification is one of the basic concepts of automated theorem proving. It concerns such questions as finding solutions of finite sets of equations, determining if every solution comes from a most general solution, and if so, determining how many most ...

Slightly Commutative Kleene Semigroups

open access: yesJournal of Algebra, 1997
Commutative Kleene semigroups are known to be rational, but Pelletier constructed a nonrational weakly commutative Kleene semigroup. We introduce slightly commutative Kleene semigroups, a class of weakly commutative Kleene semigroups, and prove that ...

On multiplicative bases in commutative semigroups

open access: yesEuropean Journal of Combinatorics, 1992
We generalize some older results on multiplicative bases of integers to a certain class of commutative semigroups.

Varieties Of Permutative Semigroups Closed Under Dominions [PDF]

open access: yesJournal of Algebraic Systems, 2023
In this paper, we partially generalize a result of Isbell from the class of commu- tative semigroups to some generalized class of commutative semigroups by showing that dominion of such semigroups belongs to the same class by using Isbell’s zigzag ...

Deviation bounds and concentration inequalities for quantum noises [PDF]

open access: yesQuantum, 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

open access: yesJournal 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]

open access: yesProceedings 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, 76–104) about determinability of finite Abelian groups by their endomorphism semigroups to finite idempotent medial ...
