BFV-BRST Quantization of 2D Supergravity
T. Fujiwara, Y. Igarashi, R. Kuriki +1
Two-dimensional supergravity theory is quantized as an anomalous gauge theory. In the Batalin-Fradkin (BF) formalism, the anomaly-canceling super-Liouville fields are introduced to…
New insight into BRST anomalies in superstring theory
T. Fujiwara, Y. Igarashi, M. Koseki +2
Based on the extended BRST formalism of Batalin, Fradkin and Vilkovisky, we perform a general algebraic analysis of the BRST anomalies in superstring theory of Neveu-Schwarz-Ramond…
Gauge Equivalence in Two--Dimensional Gravity
T. Fujiwara, Y. Igarashi, J. Kubo +1
Two-dimensional quantum gravity is identified as a second-class system which we convert into a first-class system via the Batalin-Fradkin (BF) procedure. Using the extended phase s…
Canonical treatment of two dimensional gravity as an anomalous gauge theory
T. Fujiwara, T. Tabei, Y. Igarashi +2
The extended phase space method of Batalin, Fradkin and Vilkovisky is applied to formulate two dimensional gravity in a general class of gauges. A BRST formulation of the light-con…
