Big Torelli groups: generation and commensuration
Javier Aramayona, Tyrone Ghaswala, Autumn E. Kent +3
For any surface of infinite topological type, we study the Torelli subgroup of the mapping class group , whose elements are those mapping classe…

Free products of circularly-ordered groups with amalgamated subgroup
Adam Clay, Tyrone Ghaswala
This paper gives necessary and sufficient conditions that the free product with amalgamation of circularly-ordered groups admit a circular ordering extending the given orderings of…

Mapping class groups of covers with boundary and braid group embeddings
Tyrone Ghaswala, Alan McLeay
We consider finite-sheeted, regular, possibly branched covering spaces of compact surfaces with boundary and the associated liftable and symmetric mapping class groups. In particul…
