Algebra, selections, and additive Ramsey theory
Boaz Tsaban
Hindman's celebrated Finite Sums Theorem, and its high-dimensional version due to Milliken and Taylor, are extended from covers of countable sets to covers of arbitrary topological…
Combinatorial aspects of selective star covering properties in -spaces
Boaz Tsaban
Which Isbell--Mrówka spaces (-spaces) satisfy the star version of Menger's and Hurewicz's covering properties? Following Bonanzinga and Matveev, this question is considered here…
The linear refinement number and selection theory
Michał Machura, Saharon Shelah, Boaz Tsaban
The \emph{linear refinement number} is the minimal cardinality of a centered family in such that no linearly ordered set in refines th…
Complete simultaneous conjugacy invariants in Artin's braid groups
Arkadius Kalka, Boaz Tsaban, Gary Vinokur
We solve the simultaneous conjugacy problem in Artin's braid groups and, more generally, in Garside groups, by means of a complete, effectively computable, finite invariant. This i…
Double coset problem for parabolic subgroups of braid groups
Arkadius Kalka, Mina Teicher, Boaz Tsaban
We solve the double coset problem for all parabolic subgroups of braid groups. The solution provides an effective reduction of this problem to the simultaneous conjugacy problem, a…
