The geometrical form for the string space-time action
D. S. Popović, B. Sazdović
In the present article, we derive the space-time action of the bosonic string in terms of geometrical quantities. First, we study the space-time geometry felt by probe bosonic stri…
Canonical approach to 2D induced gravity
D. S. Popovic, B. Sazdovic
Using canonical method the Liouville theory has been obtained as a gravitational Wess-Zumino action of the Polyakov string. From this approach it is clear that the form of the Liou…
The Measure from Schwinger-Dyson Equations
Aleksandar Bogojevic, Dragan S. Popovic
We review a new prescription for calculating the Lagrangian path integral measure directly from the Hamiltonian Schwinger-Dyson equations. The method agrees with the usual way of d…
2D induced gravity from canonically gauged WZNW system
M. Blagojevic, D. S. Popovic, B. Sazdovic
Starting from the Kac--Moody structure of the WZNW model for SL(2,R) and using the general canonical formalism, we formulate a gauge theory invariant under local SL(2,R) x SL(2,R)…
Path Integral Measure Via the Schwinger-Dyson Equations
Aleksandar R. Bogojević, Dragan Popović
We present a way for calculating the Lagrangian path integral measure directly from the Hamiltonian Schwinger--Dyson equations. The method agrees with the usual way of deriving the…
