Curves intersecting in a circuit pattern

Geometric Topology 2023-04-27 v3

Abstract

We show that the cycle relation between Dehn twists about curves in a circuit detects whether the circuit bounds an embedded disc. This is done by determining the isomorphism type of the group generated by said Dehn twists for various surfaces.
