报告摘要：Motivated by the Lawrence-Krammer-Bigelow representations of the classical braid groups, we study the homology of unordered configurations in an orientable genus-g surface with one boundary component, over non-commutative local systems defined from representations of the discrete Heisenberg group. We discuss the resulting representations of the mapping class groups. Joint work with Martin Palmer and Awais Shaukat, https://arxiv.org/abs/2109.00515
