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…

Hamiltonian structure of 2+1 dimensional gravity
Pietro Menotti
A summary is given of some results and perspectives of the hamiltonian ADM approach to 2+1 dimensional gravity. After recalling the classical results for closed universes in absenc…
