Relativistic Particle in Complex Space Time
Takayuki Hori
A modified version of the bilocal particle is presented in terms of complex space time. Unusual constraint structure of the model is studied, and a new concept of the physical equi…
Quantization via Star Products
Takayuki Hori, Takao Koikawa
We study quantization via star products. We investigate a quantization scheme in which a quantum theory is described entirely in terms of the function space without reference to a…
Moyal Quantization for Constrained System
Takayuki Hori, Takao Koikawa, Takuya Maki
We study the Moyal quantization for the constrained system. One of the purposes is to give a proper definition of the Wigner-Weyl(WW) correspondence, which connects the Weyl symbol…
The Problem of Time in the Quantum Theory of Black Holes
Takayuki Hori
We discuss the problem of time in spherically symmetric pure Einstein gravity with the cosmological term by using an exact solution to the Wheeler-DeWitt equation. A positive defin…
BRS Cohomology of a Bilocal Model
Takayuki Hori
We present a model in which a gauge symmetry of a field theory is intrinsic in the geometry of an extended space time itself. A consequence is that the dimension of our space time…
A Bilocal Field Theory in Four Dimensions
Takayuki Hori
A bilocal field theory having Möbius gauge invariance is proposed. In four dimensions there exists a zero momentum state of the first quantized model, which belongs to a non-trivia…
