Two-sided homological properties of special and one-relator monoids

Forum of Mathematics, Sigma
A monoid presentation is called special if the right-hand side of each defining relation is equal to 1. We prove results which relate the two-sided homological finiteness properties of a monoid defined by a special presentation with those of its group of

Extension of Paul Erdős graph on hypergroups

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
This paper introduces ultra non-commutative graphs derived from ultra non-commutative hypergroups. Vertices represent ultra non -commutative elements of the hypergroup U, defined as AU = {x ∈ U |Ǝy ∈ U, y ○ x ∩ x ○ y = ∅}. An edge connects vertices x and

Uniformly exponential growth and mapping class groups of surfaces

, 2005
We show that the mapping class group of an orientable finite type surface has uniformly exponential growth, as well as various closely related groups.
