A finitely generated variety of combinatorial inverse semigroups having uncountably many subvarieties
A finite combinatorial inverse semigroup of moderate size is presented such that the variety of combinatorial inverse semigroups generated by this semigroup posseses the following propert...

On bases of identities of finite inverse semigroups with solvable subgroups
It is shown that every finite inverse semigroup having only solvable subgroups, viewed as a semigroup with the additional unary operation of inversion, has no finite basis of identities, unless it is a strict i...

Representing structured semigroups on étale groupoid bundles
We examine a semigroup analogue of the Kumjian-Renault representation of C∗-algebras with Cartan subalgebras on twisted groupoids. Specifically, we represent semigroups with distinguished normal subsemigroups as 'slice-sections' of ...

An algebraic approach to the Weyl groupoid
We unify the Kumjian-Renault Weyl groupoid construction with the Lawson-Lenz version of Exel's tight groupoid construction. We do this by utilising only a weak algebraic fragment of the C*-algebra structure, namely its *-semigroup reduct. Fu...
