YZ Huang, J Lepowsky, L Zhang - arXiv preprint arXiv:1012.4199, 2010 - arxiv.org
This is the fifth part in a series of papers in which we introduce and develop a natural,
general tensor category theory for suitable module categories for a vertex (operator) …

The symplectic fermion ribbon quasi-Hopf algebra and the SL (2, Z)-action on its centre

V Farsad, AM Gainutdinov, I Runkel - Advances in Mathematics, 2022 - Elsevier
We introduce a family of factorisable ribbon quasi-Hopf algebras Q (N) for N a positive
integer: as an algebra, Q (N) is the semidirect product of CZ 2 with the direct sum of a …

On the semisimplicity of the category KLk for affine Lie superalgebras

D Adamović, PM Frajria, P Papi - Advances in mathematics, 2022 - Elsevier
We study the semisimplicity of the category KL k for affine Lie superalgebras and provide a
super analog of certain results from [8]. Let KL kfin be the subcategory of KL k consisting of …

On infinite order simple current extensions of vertex operator algebras

J Auger, M Rupert - arXiv preprint arXiv:1711.05343, 2017 - arxiv.org
We construct a direct sum completion $\mathcal {C} _ {\oplus} $ of a given braided monoidal
category $\mathcal {C} $ which allows for the rigorous treatment of infinite order simple …

String-net construction of RCFT correlators

J Fuchs, C Schweigert, Y Yang - arXiv preprint arXiv:2112.12708, 2021 - arxiv.org
We use string-net models to accomplish a direct, purely two-dimensional, approach to
correlators of two-dimensional rational conformal field theories. We obtain concise …

Representation theory and cohomology theory of meromorphic open string vertex algebras

F Qi - 2018 - search.proquest.com
In this dissertation we systematically study the meromorphic open-string vertex algebra, its
representation theory, and its the cohomology theory. Meromorphic open-string vertex …

Kazhdan–Lusztig equivalence and fusion of Kac modules in Virasoro logarithmic models

PV Bushlanov, AM Gainutdinov, IY Tipunin - Nuclear Physics B, 2012 - Elsevier
The subject of our study is the Kazhdan–Lusztig (KL) equivalence in the context of a one-
parameter family of logarithmic CFTs based on Virasoro symmetry with the (1, p) central …

Logarithmic CFT models from Nichols algebras: I

AM Semikhatov, IY Tipunin - Journal of Physics A: Mathematical …, 2013 - iopscience.iop.org
We construct chiral algebras that centralize rank-2 Nichols algebras with at least one
fermionic generator. This gives' logarithmic'W-algebra extensions of a fractional-level …

On the applicability of logarithmic tensor category theory

YZ Huang - arXiv preprint arXiv:1702.00133, 2017 - arxiv.org
We give results and observations which allow the application of the logarithmic tensor
category theory of Lepowsky, Zhang and the author ([HLZ1]--[HLZ9]) to more general vertex …
