Description
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 an integration over a
particular fundamental domain. The later is selected by the choice of
the minimizing functional. This construction somehow demystifies the
Gribov question.
