A lattice-ordered monoid on multilayer networks [PDF]
, 2023 In the present paper we introduce a lattice-ordered partial monoid structure on a suitable set of multilayer networks. We first study a kind of mappings that preserve the partial order and describe the order structure.

TRIANGULAR MATRIX REPRESENTATIONS OF SKEW MONOID RINGS [PDF]
, 2010 Let R be a ring and S a u.p.-monoid. Assume that there is a monoid homomorphism α : S → Aut (R). Suppose that α is weakly rigid and lR(Ra) is pure as a left ideal of R for every element a ∈ R.

Monoid valuations and value ordered supervaluations [PDF]
, 2011 OWLF 2011We complement two papers on supertropical valuation theory ([IKR1], [IKR2]) by providing natural examples of m-valuations (= monoid valuations), after that of supervaluations and transmissions between them.

Properties of the subsemigroups of the bicyclic monoid [PDF]
, 2002 In this paper we study some properties of the subsemigroups of the bicyclic monoid B, by using a recent description of its subsemigroups. We start by giving necessary and sufficient conditions for a subsemigroup to be finitely generated.

Inflations of geometric grid classes of permutations [PDF]
, 2015 All three authors were partially supported by EPSRC via the grant EP/J006440/1.Geometric grid classes and the substitution decomposition have both been shown to be fundamental in the understanding of the structure of permutation classes.

On twisted ordered monoid rings over quasi-Baer rings [PDF]
, 2011 In this paper we show that if M is an Ordered monoid then the twisted monoid ring R^T M is (left principally) quasi-Baer if and only if R is (left principally) quasi-Baer.

On Naturally Ordered Abundant Semigroups with an Adequate Monoid Transversal
, 2019 In this paper, we study a class of naturally ordered abundant semigroups with an adequate monoid transversal, namely, naturally ordered concordant semigroups with an adequate monoid transversal.

Pattern classes of permutations via bijections between linearly ordered sets [PDF]
, 2008 A pattern class is a set of permutations closed under pattern involvement or, equivalently, defined by certain subsequence avoidance conditions. Any pattern class X which is atomic, i.e.

Partially ordered case hierarchies
, 2021 Bárány A. Partially ordered case hierarchies. Glossa: a journal of general linguistics. 2021;6(1).I argue that patterns of case syncretism across languages can be modelled by partially, rather than totally, ordered case hierarchies.

Geometric inverse semigroup theory: a note on the Milnor–Schwarz lemma for inverse monoids
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract We generalise the Milnor–Schwarz lemma to inverse monoids acting on presheaves of geodesic metric spaces. We provide two proofs of this fact: one only uses elementary techniques, inspired by the arguments for group actions on metric spaces; the other involves a version of the Vietoris–Rips complex, and builds on work of Chung–Martínez–Szakács.
