Generalized Results on Monoids as Memory [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
We show that some results from the theory of group automata and monoid automata still hold for more general classes of monoids and models. Extending previous work for finite automata over commutative groups, we demonstrate a context-free language that ...

The monoid-now: a category theoretic approach to the structure of phenomenological time-consciousness [PDF]

open access: yesFrontiers in Psychology, 2023
Human consciousness is characterized by constant transitions in time. On the other hand, what is consciously experienced always possesses the temporal feature of “now.” In consciousness, “now” constantly holds different contents, yet it remains “now” no ...

S-acts over a Well-ordered Monoid with Modular Congruence Lattice

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
This work relates to the structural act theory. The structural theory includes the description of acts over certain classes of monoids or having certain properties, for example, satisfying some requirement for the congruence lattice.

A PRESENTATION FOR A SUBMONOID OF THE SYMMETRIC INVERSE MONOID

open access: yesUral Mathematical Journal, 2023
In the present paper,  we study a submonoid of the symmetric inverse semigroup \(I_n\). Specifically, we  consider the monoid of all order-, fence-, and parity-preserving transformations of \(I_n\).

Primitive orthogonal idempotents for R-trivial monoids [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
We construct a recursive formula for a complete system of primitive orthogonal idempotents for any R-trivial monoid. This uses the newly proved equivalence between the notions of R-trivial monoid and weakly ordered monoid.

Tied monoids

open access: yesSemigroup Forum, 2021
We construct certain monoids, called tied monoids. These monoids result to be semidirect products finitely presented and commonly built from braid groups and their relatives acting on monoids of set partitions. The nature of our monoids indicate that they should give origin to new knot algebras; indeed, our tied monoids include the tied braid monoid ...

Monoidal Width

open access: yesLogical Methods in Computer Science, 2023
We introduce monoidal width as a measure of complexity for morphisms in monoidal categories. Inspired by well-known structural width measures for graphs, like tree width and rank width, monoidal width is based on a notion of syntactic decomposition: a monoidal decomposition of a morphism is an expression in the language of monoidal categories, where ...

All Maximal Idempotent Submonoids of Generalized Cohypersubstitutions of Type τ = (2)

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
A generalized cohypersubstitution of type τ is a mapping σ which maps every ni-ary cooperation symbol fi to the coterm σ(f ) of type τ = (ni)i∈I. Denote by CohypG(τ) the set of all generalized cohypersubstitutions of type τ.

Prefix monoids of groups and right units of special inverse monoids

open access: yesForum of Mathematics, Sigma, 2023
A prefix monoid is a finitely generated submonoid of a finitely presented group generated by the prefixes of its defining relators. Important results of Guba (1997), and of Ivanov, Margolis and Meakin (2001), show how the word problem for certain one ...
