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.

Introduction - University of Rochester

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-

Hair History: Braids

Jun 25, 2018· Braided hair is mentioned again in the Iliad, “In blood was (Euphorbus’) hair drenched, that was like the hair of the Graces, and his tresses that were braided with gold and silver.” During the period of the Germanic Tribes (750 BC – 768 AD), the Suebian Knot braid was a very popular hairstyle for the tribe''s warriors.

1. Introduction

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

Spotlight On: Pro Staff v13 - Wilson Sporting Goods

This group will be happy to know that the RF97 features the same foam fill and double braid as the 1983 Pro Staff Original. In fact, it even weighs the same as the original (12.0oz unstrung). Finally, we’ve kept the traditional end cap on this frame’s handle, which you can order all the way up to grip size 5 (4 5/8”).

Braid group : definition of Braid group and synonyms of

The braid group B 3 is the universal central extension of the modular group PSL(2,Z), with these sitting as lattices inside the (topological) universal covering group . Further, the modular group has trivial center, and thus the modular group is isomorphic to the quotient group of modulo its center; equivalently, to the group of inner automorphisms of .. A construction is given below.

The quantum double of Drinfel’d [6] is one of the most celebrated Hopf constructions, which associates we recall the notions of braided T-egory, Turaev group algebra and generalized Yetter-Drinfel’d modules. whose object M is a left H-module (with the action h m 7!h m) and


GROUP COHOMOLOGY AND GAUGE EQUIVALENCE OF SOME TWISTED QUANTUM DOUBLES GEOFFREY MASON AND SIU-HUNG NG Abstract. We study the module egory associated to the quantum double of a nite abelian group Gtwisted by a 3-cocycle, which is known to be a braided monoidal egory, and investigate the question of when two such …

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.

Quantized multipliive quiver varieties and actions of

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.

A group of young s is sent to the front lines, where they take the aliens'' power into their bodies, and gain powerful abilities. By being violated by the enemy, they absorb their power, and defeat them while writhing in pleasure. And so the war continues. As the minds and bodies of the young s are consumed by the world.

[0907.2880] A Chern-Simons approach to Galilean quantum

Jul 16, 2009· The particular extension of the Galilei group we consider is the classical double of a much studied group, the extended homogeneous Galilei group, which is also often called Nappi-Witten group. We exhibit the Poisson-Lie structure of the doubly extended Galilei group, and quantise the Chern-Simons theory using a Hamiltonian approach.
