Reduced Hamiltonian for intersecting shells
Francesco Fiamberti, Pietro Menotti
The gauge usually adopted for extracting the reduced Hamiltonian of a thin spherical shell of matter in general relativity, becomes singular when dealing with two or more intersect…
Non invariant zeta-function regularization in quantum Liouville theory
Pietro Menotti
We consider two possible zeta-function regularization schemes of quantum Liouville theory. One refers to the Laplace-Beltrami operator covariant under conformal transformations, th…
Quantum Liouville theory with heavy charges
Pietro Menotti, Erik Tonni
We develop a general technique for solving the Riemann-Hilbert problem in presence of a number of heavy charges and a small one thus providing the exact Green functions of Liouvill…
Functional approach to (2+1) dimensional gravity
Luigi Cantini, Pietro Menotti
We work out the phase-space functional integral of the gravitational field in 2+1 dimensions interacting with N point particles in an open universe.
Polyakov conjecture and 2+1 dimensional gravity
L. Cantini, P. Menotti, D. Seminara
After briefly reviewing the hamiltonian approach to 2+1 dimensional gravity in absence of matter on closed universes, we consider 2+1 dimensional gravity coupled to point particles…
Polyakov conjecture and 2+1 dimensional gravity coupled to particles
L. Cantini, P. Menotti, D. Seminara
A proof is given of Polyakov conjecture about the auxiliary parameters of the SU(1,1) Riemann-Hilbert problem for general elliptic singularities. Such a result is related to the un…
