Absorption of Direct Factors With Respect to the Minimal Faithful Permutation Degree of a Finite Group
David Easdown, Michael Hendriksen, Neil Saunders
The minimal faithful permutation degree of a finite group is the least nonnegative integer such that embeds in the symmetric group $\Sym(n)$. We prove that if $H…
The Smallest Faithful Permutation Degree for a Direct Product Obeying an Inequality Condition
Neil Saunders, David Easdown
The minimal faithful permutation degree of a finite group is the least nonnegative integer such that embeds in the symmetric group $\Sym(n)$. Clearly $μ(G \times…
Periodic elements of the free idempotent generated semigroup on a biordered set
David Easdown, Mark Sapir, Michael Volkov
We show that every periodic element of the free idempotent generated semigroup on an arbitrary biordered set belongs to a subgroup of the semigroup.
A Presentation for the Dual Symmetric Inverse Monoid
David Easdown, James East, D. G. FitzGerald
The dual symmetric inverse monoid is the inverse monoid of all isomorphisms between quotients of an -set. We give a monoid presentation of an…
