Graded twisting of categories and quantum groups by group actions [PDF]
, 2016 Given a Hopf algebra $A$ graded by a discrete group together with an action of the same group preserving the grading, we define a new Hopf algebra, which we call the graded twisting of $A$. If the action is adjoint, this new Hopf algebra is a twist of $A$

Twenty-five years of two-dimensional rational conformal field theory [PDF]
, 2009 In this article we try to give a condensed panoramic view of the development of two-dimensional rational conformal field theory in the last twenty-five years.Comment: A review for the 50th anniversary of the Journal of Mathematical Physics.

Invertible defects and isomorphisms of rational CFTs [PDF]
, 2010 Given two two-dimensional conformal field theories, a domain wall —or defect line— between them is called invertible if there is another defect with which it fuses to the identity defect.

$\kappa$-Minkowski Spacetimes and DSR Algebras: Fresh Look and Old Problems [PDF]
, 2010 Some classes of Deformed Special Relativity (DSR) theories are reconsidered within the Hopf algebraic formulation. For this purpose we shall explore a minimal framework of deformed Weyl-Heisenberg algebras provided by a smash product construction of DSR ...

Classification of quantum groups and Belavin--Drinfeld cohomologies for orthogonal and symplectic Lie algebras [PDF]
, 2015 In this paper we continue to study Belavin-Drinfeld cohomology introduced in arXiv:1303.4046 [math.QA] and related to the classification of quantum groups whose quasi-classical limit is a given simple complex Lie algebra. Here we compute Belavin-Drinfeld

A note on permutation twist defects in topological bilayer phases [PDF]
, 2013 We present a mathematical derivation of some of the most important physical quantities arising in topological bilayer systems with permutation twist defects as introduced by Barkeshli et al. in cond-mat/1208.4834.

Quantum Isometry Group for Spectral Triples with Real Structure [PDF]
, 2010 Given a spectral triple of compact type with a real structure in the sense of [Dabrowski L., J. Geom. Phys. 56 (2006), 86-107] (which is a modification of Connes' original definition to accommodate examples coming from quantum group theory) and ...

Schur Positivity and Kirillov-Reshetikhin Modules [PDF]
, 2014 In this note, inspired by the proof of the Kirillov-Reshetikhin conjecture, we consider tensor products of Kirillov-Reshetikhin modules of a fixed node and various level.

, 2000 This paper is a continuation of math.QA/9907181 and math.QA/9908115. We consider traces of intertwiners between certain representations of the quantized enveloping algebra associated to a semisimple complex Lie algebra g, which are twisted by a ...
