Congruence lattices of finite diagram monoids
James East, James D. Mitchell, Nik Ruskuc +1
We give a complete description of the congruence lattices of the following finite diagram monoids: the partition monoid, the planar partition monoid, the Brauer monoid, the Jones m…
Maximal subsemigroups of finite transformation and diagram monoids
James East, Jitender Kumar, James D. Mitchell +1
We describe and count the maximal subsemigroups of many well-known monoids of transformations and monoids of partitions. More precisely, we find the maximal subsemigroups of the fu…
Two variants of the Froiduire-Pin Algorithm for finite semigroups
J. Jonušas, J. D. Mitchell, M. Pfeiffer
In this paper, we present two algorithms based on the Froidure-Pin Algorithm for computing the structure of a finite semigroup from a generating set. As was the case with the origi…
Structural aspects of semigroups based on digraphs
James East, Maximilien Gadouleau, James D. Mitchell
Given any digraph without loops or multiple arcs, there is a natural construction of a semigroup of transformations. To every arc of is associate…
