چکیده
We construct non-trivial quasi-quantum groups associated to any nite group G and any element of H 3 (G; U(1)). We analyze the set of representations of these algebras and show that we recover the data of particular 3-dimensional topological eld theories. We also give the R-matrix structure in non abelian RCFT orbifold models.

Orbifold Groups, Quasi-projectivity and Covers
We discuss properties of complex algebraic orbifold groups, their characteristic varieties, and their abelian covers. In particular, we deal with the question of (quasi)-projectivity of orbifold groups. We also prove a structure theorem for the variety of characters of normalcrossing quasi-projective orbifold groups. Finally, we extend Sakuma’s formula for the first Betti number of abelian cove...
متن کاملNoncommutative Probability, Matrix Models, and Quantum Orbifold Spacetimes
Inspired by the intimate relationship between Voiculescu’s noncommutative probability (of type A) and large-N matrix models in physics, we look for physical models related to noncommutative probability theory of type B. These turn out to be fermionic matrix-vector models at the double large-N limit. They describe different quantum orbifold spacetimes with boundaries. Their critical exponents co...
متن کاملOrbifold duality symmetries and quantum Hall systems, Nucl.Phys
We consider the possible role that chiral orbifold conformal field theories may play in describing the edge state theories of quantum Hall systems. This is a generalization of work that already exists in the literature, where it has been shown that 1+1 chiral bosons living on a n-dimensional torus, and which couple to a U1 gauge field, give rise to anomalous electric currents, the anomaly being...
متن کاملQuasi-quantum groups from strings
Motivated by string theory on the orbifold M/G in presence of a Kalb-Ramond field strength H , we define the operators that lift the group action to the twisted sectors. These operators turn out to generate the quasi-quantum group Dω[G], introduced in the context of conformal field theory by R. Dijkgraaf, V. Pasquier and P. Roche [1], with ω a 3-cocycle determined by a series of cohomological e...
متن کاملQuasi-isometries preserve the geometric decomposition of Haken manifolds
We prove quasi-isometry invariance of the canonical decomposition for fundamental groups of Haken 3-manifolds with zero Euler characteristic. We show that groups quasi-isometric to Haken manifold groups with nontrivial canonical decomposition are finite extensions of Haken orbifold groups. As a by-product we describe all 2-dimensional quasi-flats in the universal covers of non-geometric Haken m...
