Gauge connection between the WZNW system and 2D induced gravity
M. Blagojevic, B. Sazdovic
We introduce a consistent gauge extension of the SL(2,R) WZNW system, defined by a difference of two simple WZNW actions. By integrating out some dynamical variables in the functio…

Conservation Laws in Poincaré Gauge Theory
M. Blagojević
Basic features of the conservation laws in the Hamiltonian approach to the Poincaré gauge theory are presented. It is shown that the Hamiltonian is given as a linear combination of…

The Liouville Theory and SL(2,R) Symmetry
M. Blagojevic
The Liouville action emerges as the effective action of 2-d gravity in the process of path integral quantization of the bosonic string. It yields a measure of the violation of clas…
