Rosatti's Theorem
There is a one-to-one correspondence between the sets of equivalent correspondences (not of value 0) on an irreduciblecurve of Genus (Curve) 
, and the rational Collineations of a projective space of 
dimensions whichleave invariant a space of 
dimensions. The number of linearly independent correspondences will be that of linearlyindependent Collineations.
