Algorithmic properties of inverse monoids with hyperbolic and tree-like Schützenberger graphs
Robert D. Gray, Pedro V. Silva, Nóra Szakács
We prove that the class of finitely presented inverse monoids whose Schützenberger graphs are quasi-isometric to trees has a uniformly solvable word problem, furthermore, the langu…

On F-inverse covers of finite-above inverse monoids
Nóra Szakács, Mária B. Szendrei
Finite-above inverse monoids are a common generalization of finite inverse monoids and Margolis--Meakin expansions of groups. Given a finite-above -unitary inverse monoid an…
