The semi-classical saddles in three-dimensional gravity via holography and mini-superspace approach
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We determine the complex geometries dual to the semi-classical saddles in three-dimensional gravity with positive or negative cosmological constant. We examine the semi-classical s…
Semi-classical saddles of three-dimensional gravity via holography
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We find out the complex geometries corresponding to the semi-classical saddles of threedimensional quantum gravity by making use of the known results of dual conformal field theory…
Complex saddles of Chern-Simons gravity and dS/CFT correspondence
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We examine the black hole solutions of dS gravity by applying the explicit dS/CFT correspondence. The gravity theory is described by Chern-Simons theory with complex ga…
Complex saddles of three-dimensional de Sitter gravity via holography
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We determine complex saddles of three-dimensional gravity with a positive cosmological constant by applying the recently proposed holography. It is sometimes useful to consider a c…
Argyres-Douglas Theories, S-duality and AGT Correspondence
Takuya Kimura, Takahiro Nishinaka, Yuji Sugawara +1
We propose a Nekrasov-type formula for the instanton partition functions of four-dimensional N=2 U(2) gauge theories coupled to (A_1,D_{2n}) Argyres-Douglas theories. This is carri…

Tadashi Takayanagi, Takahiro Uetoko
In this paper we provide a Chern-Simons gravity dual of a two dimensional conformal field theory on a manifold with boundaries, so called boundary conformal field theory (BCFT). We…

Thomas Creutzig, Yasuaki Hikida, Takahiro Uetoko
We examine rectangular W-algebras with or symmetry, which can be realized as the asymptotic symmetry of higher spin gravities with restricted matrix extensions. We…
Argyres-Douglas theories and Liouville Irregular States
Takahiro Nishinaka, Takahiro Uetoko
We study irregular states of rank-two and three in Liouville theory, based on an ansatz proposed by D. Gaiotto and J. Teschner. Using these irregular states, we evaluate asymptotic…

Yasuaki Hikida, Takahiro Uetoko
We compute the superconformal blocks from the networks of open Wilson lines in the Chern-Simons theory in the expansion of large central charge $c…

Yasuaki Hikida, Takahiro Uetoko
We examine three point functions with two scalar operators and a higher spin current in 2d W_N minimal model to the next non-trivial order in 1/N expansion. The minimal model was p…
