Weyl Groups in AdS(3)/CFT(2)
Masafumi Fukuma, Takeshi Oota, Hirokazu Tanaka
The system of D1 and D5 branes with a Kaluza-Klein momentum is re-investigated using the five-dimensional U-duality group E_{6(+6)}(Z). We show that the residual U-duality symmetry…
Comments on T-dualities of Ramond-Ramond Potentials
Masafumi Fukuma, Takeshi Oota, Hirokazu Tanaka
The type IIA/IIB effective actions compactified on T^d are known to be invariant under the T-duality group SO(d, d; Z) although the invariance of the R-R sector is not so direct to…
The Relation between Mixed Boundary States in Two- and Three- Matrix Models
Masahiro Anazawa, Atushi Ishikawa, Hirokazu Tanaka
We discuss the relation among some disk amplitudes with non-trivial boundary conditions in two-dimensional quantum gravity. They are obtained by the two-matrix model as well as the…
Interaction of boundaries with heterogeneous matter states in matrix models
Masahiro Anazawa, Atushi Ishikawa, Hirokazu Tanaka
We study disk amplitudes whose boundary conditions on matter configurations are not restricted to homogeneous ones. They are examined in the two-matrix model as well as in the thre…
