Quivers, Floer Cohomology, and Braid Group Actions
1a. Generalities. This paper investigates the connection between symplectic geometry and those parts of representation theory which revolve around the notion of categorification. The existence of such a connection, in an abstract sense, follows from simple general ideas. The difficult thing is to make it explicit. On the symplectic side, the tools needed for a systematic study of this question ...
متن کاملEnhanced gauge symmetry and braid group actions
Enhanced gauge symmetry appears in Type II string theory (as well as Fand M-theory) compactified on Calabi–Yau manifolds containing exceptional divisors meeting in Dynkin configurations. It is shown that in many such cases, at enhanced symmetry points in moduli a braid group acts on the derived category of sheaves of the variety. This braid group covers the Weyl group of the enhanced symmetry a...
متن کاملBraid Group Actions and Tensor Products
We define an action of the braid group of a simple Lie algebra on the space of imaginary roots in the corresponding quantum affine algebra. We then use this action to determine an explicit condition for a tensor product of arbitrary irreducible finite–dimensional representations is cyclic. This allows us to determine the set of points at which the corresponding R–matrix has a zero. 0. Introduct...
متن کاملBraid Group Actions via Categorified Heisenberg Complexes
We construct categorical braid group actions from 2-representations of a Heisenberg algebra. These actions are induced by certain complexes which generalize spherical (Seidel-Thomas) twists and are reminiscent of the Rickard complexes defined by Chuang-Rouquier. Conjecturally, one can relate our complexes to Rickard complexes using categorical vertex operators.
متن کاملJumps in Cohomology and Free Group Actions
A discrete group G has periodic cohomology over R if there is an element in a cohomology group, cup product with which induces an isomorphism in cohomology after a certain dimension. Adem and Smith showed if R = Z, then this condition is equivalent to the existence of a finite dimensional free-G-CWcomplex homotopy equivalent to a sphere. It has been conjectured by Olympia Talelli, that if G is ...
