1207.5210 (Laurent Baulieu et al.)

Minimizing gauge-functional for 2-d gravity and string theory    [PDF]

Laurent Baulieu, Daniel Zwanziger
We show the existence of a minimizing procedure for selecting a unique representative on the orbit of any given Riemann surface that contributes to the string partition function. As it must, the procedure reduces the string path integral to a final integration over a particular fundamental domain, selected by the choice of the minimizing functional. This construction somehow demystifies the Gribov question.
