CFT duals of three-dimensional de Sitter gravity

Y Hikida, T Nishioka, T Takayanagi, Y Taki - Journal of High Energy …, 2022 - Springer
A bstract We present a class of dS/CFT correspondence between two-dimensional CFTs
and three-dimensional de Sitter spaces. We argue that such a CFT includes an SU (2) WZW …

Holography in de Sitter space via Chern-Simons gauge theory

Y Hikida, T Nishioka, T Takayanagi, Y Taki - Physical Review Letters, 2022 - APS
In this Letter, we propose a holographic duality for classical gravity on a three-dimensional
de Sitter space. We first show that a pair of SU (2) Chern-Simons gauge theories reproduces …

A QFT for non-semisimple TQFT

T Creutzig, T Dimofte, N Garner, N Geer - arXiv preprint arXiv:2112.01559, 2021 - arxiv.org
We construct a family of 3d quantum field theories $\mathcal T_ {n, k}^ A $ that conjecturally
provide a physical realization--and derived generalization--of non-semisimple mathematical …

Trialities of -algebras

T Creutzig, AR Linshaw - arXiv preprint arXiv:2005.10234, 2020 - arxiv.org
We prove the conjecture of Gaiotto and Rap\v {c}\'ak that the $ Y $-algebras $ Y_ {L, M,
N}[\psi] $ with one of the parameters $ L, M, N $ zero, are simple one-parameter quotients of …

Tensor categories for vertex operator superalgebra extensions

T Creutzig, S Kanade, R McRae - arXiv preprint arXiv:1705.05017, 2017 - arxiv.org
Let $ V $ be a vertex operator algebra with a category $\mathcal {C} $ of (generalized)
modules that has vertex tensor category structure, and thus braided tensor category …

Trialities of orthosymplectic W-algebras

T Creutzig, AR Linshaw - Advances in Mathematics, 2022 - Elsevier
Trialities of W-algebras are isomorphisms between the affine cosets of three different W-
(super) algebras, and were first conjectured in the physics literature by Gaiotto and Rapčák …

Schur–Weyl duality for Heisenberg cosets

T Creutzig, S Kanade, AR Linshaw, D Ridout - Transformation Groups, 2019 - Springer
Let V be a simple vertex operator algebra containing a rank n Heisenberg vertex algebra H
and let C= Com (H; V) be the coset of H in V. Assuming that the module categories of interest …

Chiral algebras of class and Moore-Tachikawa symplectic varieties

T Arakawa - arXiv preprint arXiv:1811.01577, 2018 - arxiv.org
We give a functorial construction of the genus zero chiral algebras of class $\mathcal {S} $,
that is, the vertex algebras corresponding to the theory of class $\mathcal {S} $ associated …

Aspects of -deformed M-theory

D Gaiotto, J Oh - arXiv preprint arXiv:1907.06495, 2019 - arxiv.org
We explore the properties of $\Omega $-deformed M-theory, with particular focus on the
$\mathbb {C} _ {\epsilon_1}\times\mathbb {C} _ {\epsilon_2}\times\mathbb {C} _ {\epsilon_3} …

Gluing vertex algebras

T Creutzig, S Kanade, R McRae - Advances in Mathematics, 2022 - Elsevier
We relate commutative algebras in braided tensor categories to braid-reversed tensor
equivalences, motivated by vertex algebra representation theory. First, for C a braided …
