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…
