  Special Bohr - Sommerfeld geometry, first formulated for simply connected
symplectic manifolds (or for simple connected algebraic varieties), gives rise
to some natural problems for the simplest example in non simply connected case.
Namely for any algebraic curve one can define a correspondence between
holomorphic differentials and certain finite graphs. Here we ask some natural
questions appear with this correspondence. It is a partial answer to the
question of A. Varchenko about possibility of applications of Special Bohr
-Sommerfeld geometry in non simply connected case. The russian version has been
translated.
