Generating the liftable mapping class groups of regular cyclic covers

Soumya Dey, Neeraj K. Dhanwani, Harsh Patil +1

Let $Mod (S_{g})$ be the mapping class group of the closed orientable surface of genus $g \geq 1$ , and let $LMod_{p} (X)$ be the liftable mapping class group associat…

Liftable mapping class groups of regular cyclic covers

Nikita Agarwal, Soumya Dey, Neeraj K. Dhanwani +1

Let $Mod (S_{g})$ be the mapping class group of the closed orientable surface of genus $g \geq 1$ . For $k \geq 2$ , we consider the standard $k$ -sheeted regular cover $p_k: S_…

Commutator Subgroups of Singular Braid Groups

Soumya Dey, Krishnendu Gongopadhyay

The singular braids with $n$ strands, $n \geq 3$ , were introduced independently by Baez and Birman. It is known that the monoid formed by the singular braids is embedded in a group…

Commutator Subgroups of Twin Groups and Grothendieck's Cartographical Groups

Soumya Dey, Krishnendu Gongopadhyay

Let $T W_{n}$ be the twin group on $n$ arcs, $n \geq 2$ . The group $T W_{m + 2}$ is isomorphic to Grothendieck's $m$ -dimensional cartographical group $C_{m}$ , $m \geq 1$ . In this…

Commutator Subgroups of Welded Braid Groups

Soumya Dey, Krishnendu Gongopadhyay

Let $W B_{n}$ be the welded (or loop) braid group on n strands, $n \geq 3$ . We investigate commutator subgroup of $W B_{n}$ . We prove that the commutator subgroup $W B_{n}^{'}$ is finitely gen…
