Wick Rotation and Abelian Bosonization

Aleksandar Bogojevic, Olivera Miskovic

We investigate the connection between Abelian bosonization in the Minkowski and Euclidean formalisms. The relation is best seen in the complex time formalism of S. A. Fulling and S…

Abelian Bosonization, the Wess-Zumino Functional and Conformal Symmetry

A. Bogojevic, B. Sazdovic, O. Miskovic

We look at the equivalence of the massive Thirring and sine-Gordon models. Previously, this equivalence was derived perturbatively in mass (though to all orders). Our calculation g…

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…

The Role of Conformal Symmetry in Abelian Bosonization of the Massive Thirring Model

Aleksandar Bogojevic, Branislav Sazdovic, Olivera Miskovic

We show equivalence between the massive Thirring model and the sine-Gordon theory by gauge fixing a wider gauge invariant theory in two different ways. The exact derivation of the…

Black Holes Without Singularities

Aleksandar Bogojevic, Dejan Stojkovic

We study the properties of a completely integrable deformation of the CGHS dilaton gravity model in two dimensions. The solution is shown to represent a singularity free black hole…

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…
