Let X be a geometrically irreducible smooth projective curve defined over the real numbers. Let n X be the number of connected components of the locus of real points of X. Let x 1 , . . . , x be real points from distinct components, with < n X . We prove that the divisor x 1 + • • • + x is rigid. We
