Involutions of (twisted) diagram monoids
James East, P. A. Azeef Muhammed
We classify the involutions of all of the most well-studied diagram monoids -- namely the partition, planar partition, partial Brauer, Motzkin, Brauer and Temperley--Lieb monoids -…
Categorical representation of DRC-semigroups
James East, Matthias Fresacher, P. A. Azeef Muhammed +1
DRC-semigroups model associative systems with domain and range operations, and contain many important classes, such as inverse, restriction, Ehresmann, regular -, and -regula…
Projection algebras and free projection- and idempotent-generated regular -semigroups
James East, Robert D. Gray, P. A. Azeef Muhammed +1
The purpose of this paper is to introduce a new family of semigroups - the free projection-generated regular -semigroups - and initiate their systematic study. Such a semigroup…
