Abstract
A labelled oriented graph (LOG) group is a group given by a presentation constructed in a certain way from a labelled oriented graph: examples include
Wirtinger presentations of knot groups. We show how to obtain generators for the Schur Multiplier H2(G) of a LOG group from the underlying LOG,
and by exhibiting the n-string braid group Bn as a LOG group, we compute H2(Bn).
