Diffeomorphism invariant measure for finite dimensional geometries
Pietro Menotti, Pier Paolo Peirano
We consider families of geometries of D--dimensional space, described by a finite number of parameters. Starting from the De Witt metric we extract a unique integration measure whi…
Functional integration on two dimensional Regge geometries
Pietro Menotti, Pier Paolo Peirano
By adopting the standard definition of diffeomorphisms for a Regge surface we give an exact expression of the Liouville action both for the sphere and the torus topology in the dis…
Conformal gauge fixing and Faddeev-Popov determinant in 2-dimensional Regge gravity
Pietro Menotti, Pier Paolo Peirano
By regularizing the conical singularities by means of a segment of a sphere or pseudosphere and then taking the regulator to zero, we compute exactly the Faddeev--Popov determinant…
Faddeev-Popov determinant in 2-dimensional Regge gravity.
Pietro Menotti, Pier Paolo Peirano
By regularizing the singularities appearing in the two dimensional Regge calculus by means of a segment of a sphere or pseudo-sphere and then taking the regulator to zero, we obtai…
