Homological and Monodromy Representations of Framed Braid Groups

Abstract

Abstract. In this paper, we introduce two new classes of representations of the framed braid groups. One is the homological representation constructed as the action of a mapping class group on a certain homology group. The other is the monodromy representation of the confluent KZ equation, which is a generalization of the KZ equation to have irregular singularities. We also give a conjectural equivalence between these two classes of representations.

Irregular vertex algebras

“…) O is non-empty. The (proof of) Lemma 4.3 in[Ike18] implies that the singularity ofM (r) c,h is H = {λ r = 0}. Hence we obtain (5).…”
