, 2016 A new category of algebro-geometric objects is defined. This construction is a vast generalization of existing F1-theories, as it contains the the theory of monoid schemes on the one hand and classical algebraic theory, e.g.

Theory of Computing Systems, 2013 The author develops an algebraic theory for languages of data words, i.e. words over an alphabet \(\Sigma\times \mathbb{D}\) where \(\Sigma\) is a finite set of labels and \(\mathbb{D}\) is an infinite set of data values. Some of the key notions of the paper are defined relative to a given data symmetry \((\mathbb{D},G)\) in which \(G\) is a subgroup ...

On endomorphisms of groups of orders 37–47; pp. 137–150 [PDF]
Proceedings of the Estonian Academy of Sciences, 2017 It is proved that the finite groups of orders 37â47 are determined by their endomorphism monoids in the class of all groups.

Factoring Continuous Characters Defined on Subgroups of Products of Topological Groups
Axioms, 2021 This study is on the factorization properties of continuous homomorphisms defined on subgroups (or submonoids) of products of (para)topological groups (or monoids).

, 2002 We construct a new monoid structure for Artin groups associated with finite Coxeter systems. This monoid shares with the classical positive braid monoid a crucial algebraic property: it is a Garside monoid.

A Categorical Approach to Syntactic Monoids [PDF]
Logical Methods in Computer Science, 2018 The syntactic monoid of a language is generalized to the level of a symmetric monoidal closed category $\mathcal D$. This allows for a uniform treatment of several notions of syntactic algebras known in the literature, including the syntactic monoids of ...

Realizable sets of catenary degrees of numerical monoids
, 2017 The catenary degree is an invariant that measures the distance between factorizations of elements within an atomic monoid. In this paper, we classify which finite subsets of $\mathbb Z_{\ge 0}$ occur as the set of catenary degrees of a numerical monoid ...

On locally compact shift-continuous topologies on the α-bicyclic monoid
Topological Algebra and its Applications, 2018 A topology τ on a monoid S is called shift-continuous if for every a, b ∈ S the two-sided shift S → S, x ↦ axb, is continuous. For every ordinal α ≤ ω, we describe all shift-continuous locally compact Hausdorff topologies on the α-bicyclic monoid Bα ...

SOLVING DIFFERENCE EQUATIONS IN SEQUENCES: UNIVERSALITY AND UNDECIDABILITY
Forum of Mathematics, Sigma, 2020 We study solutions of difference equations in the rings of sequences and, more generally, solutions of equations with a monoid action in the ring of sequences indexed by the monoid. This framework includes, for example, difference equations on grids (for
