### Summer REU info- Vic Reiner - University of Minnesota

For double covers, the voltage graph is a signed graph with critical group defined in terms a Laplacian matrix that appears in work of Zaslavsky. One can generalize this to a notion of "double coverings" of signed graphs, and use this to reinterpret a result of H. Bai on the p-primary structure of the critical groups of n-cubes for odd primes p.

whose fundamental group is the braid group of the 2-sphere or real projective plane respectively. The resulting spaces are elementary ﬂavors of moduli spaces and may be described in elementary terms as spaces of polynomials. These were investigated in []. One feature of the view here is that when calculations “work”, they do so eas-

ping class group of its orientable double cover Scontaining no (powers of) Dehn twists. Thus, from every eedding ϕ: Bn → M(N) we can obtain an eedding ψ: Bn → M(S), whose image contains no Dehn twists. In Section 3 we use the fact that the braid group is isomorphic to the mapping class group of a punctured disc, to construct an eedding

### Characteristics of Graph Braid Groups | SpringerLink

Research on graph braid groups has mainly been concentrated on characteristics of their presentations. An outstanding question was which graph braid group is a right-angled Artin group. The precise characterization of such graphs was given in [ 12] for n ≥5 by extending the result in [ 8] for trees and n ≥4.

In this case, for any n E Z>o, we construct a functor from the egory of Dq-modules to representations of the type A double affine Hecke algebra of rank n. This functor is an instance of a more general construction which may be applied to any quasi-triangular Hopf algebra H, and yields representations of the elliptic braid group of rank n.

### Chelsea Walton - Research - Department of Mathematics

Abstract: We define the universal quantum group H that preserves a pair of Hopf comodule maps, whose underlying vector space maps are preregular forms defined on dual vector spaces. This generalizes the construction of Bichon and Dubois-Violette (2013), where the target of these comodule maps are the ground field.
