Weyl Invariance and Spurious Black Hole in Two-Dimensional Dilaton Gravity
Takanori Fujiwara, Yuji Igarashi, Jisuke Kubo
In two-dimensional dilaton gravity theories, there may exist a global Weyl invariance which makes black hole spurious. If the global invariance and the local Weyl invariance of the…
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…
Unrecognizable Black Holes in Two Dimensions
T. Fujiwara, Y. Igarashi, J. Kubo
The classical 2D cosmological model of Callan, Giddings, Harvey and Strominger possesses a global symmetry that is responsible for decoupling of matter fields. The model is quantiz…
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…
