Binary patterns in the Prouhet-Thue-Morse sequence [PDF]
Discrete Mathematics & Theoretical Computer Science, 2021 We show that, with the exception of the words $a^2ba^2$ and $b^2ab^2$, all (finite or infinite) binary patterns in the Prouhet-Thue-Morse sequence can actually be found in that sequence as segments (up to exchange of letters in the infinite case).

Notes on a semigroup related to the dicyclic group Qn [PDF]
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 We consider certain properties of the semigroup S defined by the Presentation S = 〈a,b : a2ⁿ⁻¹ = 1,b2 = a2ⁿ⁻², ba = ab2ⁿ⁻¹-1〉, (n ≥ 3).

Homological Finiteness Conditions for Groups, Monoids, and Algebras
Communications in Algebra, 2006 Recently Alonso and Hermiller introduced a homological finiteness condition\break $bi{-}FP_n$ (here called {\it weak} $bi{-}FP_n$) for monoid rings, and Kobayashi and Otto introduced a different property, also called $bi{-}FP_n$ (we adhere to their ...

Prefix monoids of groups and right units of special inverse monoids
Forum 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 ...

Veterinary Dermatology, Volume 32, Issue 6, Page 668-e178, December 2021., 2021 Background Antimicrobial resistance in Staphylococcus pseudintermedius (SP) and the prevalence of meticillin‐resistant SP (MRSP) is increasing in dogs worldwide. Objectives To evaluate the influence of hospital size on antimicrobial resistance of SP and whether restricted use of antimicrobials based on antibiograms could reduce the identification of ...

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

Factoriality and the Pin-Reutenauer procedure [PDF]
Discrete Mathematics & Theoretical Computer Science, 2016 We consider implicit signatures over finite semigroups determined by sets of pseudonatural numbers. We prove that, under relatively simple hypotheses on a pseudovariety V of semigroups, the finitely generated free algebra for the largest such signature ...

Pseudometric spaces: From minimality to maximality in the groups of combinatorial self-similarities
Analysis and Geometry in Metric Spaces, 2023 The group of combinatorial self-similarities of a pseudometric space (X,d)\left(X,d) is the maximal subgroup of the symmetric group Sym(X){\rm{Sym}}\left(X) whose elements preserve the four-point equality d(x,y)=d(u,v)d\left(x,y)=d\left(u,v).

On an equivalence between regular ordered Γ-semigroups and regular ordered semigroups
Open Mathematics, 2020 In this paper, we develop a technique which enables us to obtain several results from the theory of Γ-semigroups as logical implications of their semigroup theoretical analogues.

Strong conciseness in profinite groups
Journal of the London Mathematical Society, Volume 102, Issue 3, Page 977-993, December 2020., 2020 Abstract A group word w is said to be strongly concise in a class C of profinite groups if, for every group G in C such that w takes less than 2ℵ0 values in G, the verbal subgroup w(G) is finite. Detomi, Morigi and Shumyatsky established that multilinear commutator words — and the particular words x2 and [x2,y] — have the property that the ...
