An effective Hamiltonian for 2D black hole Physics
D. G. Delfrate, F. P. Devecchi, D. F. Marchioro
In another application of the methods of Henneaux, Teitelboim, and Vergara developed for diffeomorphisms invariant models, the CGHS theory of 2D black holes is focused in order to…
A solution to the zero-hamiltonian problem in 2-D gravity
C. P. Constantinidis, F. P. Devecchi, D. F. Marchioro
The zero-hamiltonian problem, present in reparametrization invariant systems, is solved for the 2-D induced gravity model. Working with methods developed by Henneaux et al. we find…
Two-dimensional N=1,2 Supersymmetric Chiral and Dual Models
C. P. Constantinidis, F. P. Devecchi, F. Toppan
Two-dimensional N=1,2 supersymmetric chiral models and their dual extensions are introduced and canonically quantized. Working within a superspace formalism, the non-manifest invar…
2-D gravity and the extended formalism
Fernando P. Devecchi
The role of symmetry in two-dimensional gravity is investigated in the context of the extended hamiltonian formalism. Using our results we clarify previous works on the…
Symmetries and degrees of freedom in 2-dimensional dual models
C. P. Constantinidis, F. P. Devecchi
The 2-dimensional version of the Schwarz and Sen duality model (Tseytlin model) is analyzed at the classical and quantum levels. The solutions are obtained after removing the gauge…
Covariant path integral for chiral p-forms
Fernando P. Devecchi, Marc Henneaux
The covariant path integral for chiral bosons obtained by McClain, Wu and Yu is generalized to chiral p-forms. In order to handle the reducibility of the gauge transformations asso…
