Beyond Wilson? Carroll from current deformations
Arjun Bagchi, Aritra Banerjee, Saikat Mondal +2
At extreme energies, both low and high, the spacetime symmetries of relativistic quantum field theories (QFTs) are expected to change with Galilean symmetries emerging in the very…
Boosting to BMS
Arjun Bagchi, Aritra Banerjee, Hisayoshi Muraki
Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll symmetries, are intrinsically associated to null manifolds and in two dimensions can be obtained as an In{ö}…
The null identities for boundary operators in the minimal gravity
Goro Ishiki, Hisayoshi Muraki, Chaiho Rim
By using the matrix-model representation, we show that correlation numbers of boundary changing operators (BCO) in minimal Liouville gravity satisfy some identities, whi…
From minimal gravity to open intersection theory
Alexander Alexandrov, Hisayoshi Muraki, Chaiho Rim
We investigated the relation between the two-dimensional minimal gravity (Lee-Yang series) with boundaries and open intersection theory. It is noted that the minimal gravity with b…
Open KdV hierarchy of 2d minimal gravity of Lee-Yang series
Hisayoshi Muraki, Chaiho Rim
We present the open KdV hierarchy of 2d minimal gravity of Lee-Yang series which uses the boundary cosmological constant as a flow parameter. The boundary cosmological constant is…
Information metric, Berry connection and Berezin-Toeplitz quantization for matrix geometry
Goro Ishiki, Takaki Matsumoto, Hisayoshi Muraki
We consider the information metric and Berry connection in the context of noncommutative matrix geometry. We propose that these objects give a new method of characterizing the fuzz…
Open KdV hierarchy and minimal gravity on disk
Aditya Bawane, Hisayoshi Muraki, Chaiho Rim
We show that the minimal gravity of Lee-Yang series on disk is a solution to the open KdV hierarchy proposed for the intersection theory on the moduli space of Riemann surfaces wit…
Commutative Geometry for Non-commutative D-branes by Tachyon Condensation
Tsuguhiko Asakawa, Goro Ishiki, Takaki Matsumoto +2
There is a difficulty in defining the positions of the D-branes when the scalar fields on them are non-abelian. We show that we can use tachyon condensation to determine the positi…
Dual Frobenius manifolds of minimal gravity on disk
Aditya Bawane, Hisayoshi Muraki, Chaiho Rim
Liouville field theory approach to 2-dimensional gravity possesses the duality (). The matrix counterpart of minimal gravity ( co-…
Contravariant geometry and emergent gravity from noncommutative gauge theories
Yukio Kaneko, Hisayoshi Muraki, Satoshi Watamura
We investigate a relation of the contravariant geometry to the emergent gravity from noncommutative gauge theories. We give a refined formulation of the contravariant gravity and p…
Contravariant Gravity on Poisson Manifolds and Einstein Gravity
Yukio Kaneko, Hisayoshi Muraki, Satoshi Watamura
A relation between gravity on Poisson manifolds proposed in arXiv:1508.05706 and Einstein gravity is investigated. The compatibility of the Poisson and Riemann structures defines a…
Kähler structure in the commutative limit of matrix geometry
Goro Ishiki, Takaki Matsumoto, Hisayoshi Muraki
We consider the commutative limit of matrix geometry described by a large- sequence of some Hermitian matrices. Under some assumptions, we show that the commutative geometry pos…
Gravity theory on Poisson manifold with -flux
Tsuguhiko Asakawa, Hisayoshi Muraki, Satoshi Watamura
A novel gravity theory based on Poisson Generalized Geometry is investigated. A gravity theory on a Poisson manifold equipped with a Riemannian metric is constructed from a contrav…
Topological T-duality via Lie algebroids and -flux in Poisson-generalized geometry
T. Asakawa, H. Muraki, S. Watamura
It is known that the topological T-duality exchanges and -fluxes. In this paper, we reformulate the topological T-duality as an exchange of two Lie algebroids in the general…
Poisson-generalized geometry and -flux
T. Asakawa, H. Muraki, S. Sasa +1
We study a new kind of Courant algebroid on Poisson manifolds, which is a variant of the generalized tangent bundle in the sense that the roles of tangent and the cotangent bundle…
Generalized geometry and nonlinear realization of generalized diffeomorphism on D-brane effective action
T. Asakawa, H. Muraki, S. Sasa +1
The characterization of the DBI action of a Dp-brane using the generalized geometry is discussed. It is shown that the DBI action is invariant under the diffeomorphism and B-transf…

T. Asakawa, H. Muraki, S. Watamura
The properties of the D-brane fluctuations are investigated using the two types of deformation of the Dirac structure, based on the B-transformation and the beta-transformation, re…
