Pathological computations of Mackey functor‐valued Tor over cyclic groups
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 3024-3036, October 2025.Abstract In equivariant algebra, Mackey functors play the role of abelian groups and Green and Tambara functors play the role of commutative rings. In this paper, we compute Mackey functor‐valued Tor over certain free Green and Tambara functors, generalizing the computation of Tor over a polynomial ring on one generator.

Motivic p$p$‐adic tame cohomology
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 3194-3210, October 2025.Abstract We construct a comparison functor between (A1$\mathbf {A}^1$‐local) tame motives and (□¯${\overline{\square }}$‐local) log‐étale motives over a field k$k$ of positive characteristic. This generalizes Binda–Park–Østvær's comparison for the Nisnevich topology.

Notes on Number Theory and Discrete MathematicsThe set of Set(n)'s for natural numbers n is constructed. For this set it is proved that it is a commutative semi-group. The conditions for which it is a monoid are given.

On Almost Everywhere K-Additive Set-Valued Maps
Annales Mathematicae SilesianaeLet X be an Abelian group, Y be a commutative monoid, K ⊂Y be a submonoid and F : X → 2Y \ {∅} be a set-valued map. Under some additional assumptions on ideals ℐ1 in X and ℐ2 in X2, we prove that if F is ℐ2-almost everywhere K-additive, then there ...

Endomorphism monoids of acts over monoids
Semigroup Forum, 1973 In this paper we investigate under which conditions a monoid R is defined by the endomorphism monoid of an act over R. More precisely, we ask when an isomorphism between two such endomorphism monoids over monoids R1 and R2 is induced by a semilinear isomorphism. The question is considered also for ordered and for topological monoids.

The join of split graphs whose completely regular endomorphisms form a monoid
Open Mathematics, 2017 In this paper, completely regular endomorphisms of the join of split graphs are investigated. We give conditions under which all completely regular endomorphisms of the join of two split graphs form a monoid.

Factorizable inverse monoids [PDF]
Semigroup Forum, 2009 An inverse monoid \(S\) is called `factorizable' provided that it decomposes into a product \(UE\) of its group \(U\) of units and its semi-lattice \(E\) of idempotents. The paper under review is a survey of the algebraic theory of factorizable inverse monoids. The paper starts with a short historical overview. This goes over to the structure theory of

On Ideals of Submonoids of Power Monoids
MathematicsLet S be a numerical monoid, while a Pfin(S)-monoid S is a monoid generated by a finite number of finite non-empty subsets of S. That is, S is a non-cancellative commutative monoid obtained from the sumset of finite non-negative integer sets.

A criterion of the existence of an embedding of a monothetic monoid into a topological group
Topological Algebra and its Applications, 2019 Using properties of unitary Cauchy filters on monothetic monoids, we prove a criterion of the existence of an embedding of such a monoid into a topological group.
