Deformed fields and Moyal construction of deformed super Virasoro algebra
R. Kemmoku, H. T. Sato
Studied is the deformation of super Virasoro algebra proposed by Belov and Chaltikhian. Starting from abstract realizations in terms of the FFZ type generators, various connections…
D=5 Simple Supergravity on AdS_2 \times S^3
Akira Fujii, Ryuji Kemmoku
The Kaluza-Klein spectrum of D=5 simple supergravity compactified on S^3 is studied. A classical background solution which preserves maximal supersymmetry is fulfilled by the geome…
D=5 Simple Supergravity on AdS_{3} x S^{2} and N=4 Superconformal Field Theory
A. Fujii, R. Kemmoku, S. Mizoguchi
We study the Kaluza-Klein spectrum of D=5 simple supergravity on with special interest in the relation to a two-dimensional N=4 superconformal field theory. The spectrum is o…
Difference Operator Approach to the Moyal Quantization and Its Application to Integrable Systems
Ryuji Kemmoku
Inspired by the fact that the Moyal quantization is related with nonlocal operation, I define a difference analogue of vector fields and rephrase quantum description on the phase s…
Phase Space Discretization and Moyal Quantization
Ryuji Kemmoku, Satoru Saito
The Moyal quantization is described as a discretization of the classical phase space by using difference analogue of vector fields. Difference analogue of Lie brackets plays the ro…
as a Discretization of Virasoro Algebra
Ryuji KEMMOKU, Satoru SAITO, 13 pages +1
It is shown that the algebra is nothing but the simplest subalgebra of a -discretized \vi\ algebra, in the language of the KP hierarchy explicitly.
