Rigidity of braid group actions on and of low-genus mapping class group actions on
Idrissa Ba, Adam Clay, Tyrone Ghaswala
Every nontrivial action of the braid group on by orientation-preserving homeomorphisms yields, up to conjugation by a homeomorphism of , a representa…
Knot groups, quandle extensions and orderability
Idrissa Ba, Mohamed Elhamdadi
This paper gives a new way of characterizing L-space -manifolds by using orderability of quandles. Hence, this answers a question of Adam Clay et al. [Question 1.1 of Canad. Mat…
Circular orderability and quandles
Idrissa Ba, Mohamed Elhamdadi
In this paper, we introduce the notion of circular orderability for quandles. We show that the set all right (respectively left) circular orderings of a quandle is a compact topolo…
The number of locally invariant orderings of a group
Idrissa Ba, Adam Clay, Ian Thompson
We show that if a nontrivial group admits a locally invariant ordering, then it admits uncountably many locally invariant orderings. For the case of a left-orderable group, we prov…
Circular orderability of 3-manifold groups
Idrissa Ba, Adam Clay
This paper initiates the study of circular orderability of -manifold groups, motivated by the L-space conjecture. We show that a compact, connected, -irreducible $…
The space of circular orderings and semiconjugacy
Adam Clay, Idrissa Ba
Work of Linnell shows that the space of left-orderings of a group is either finite or uncountable, and in the case that the space is finite, the isomorphism type of the group is kn…
