Prym differential : ウィキペディア英語版 | Prym differential In mathematics, a Prym differential of a Riemann surface is a differential form on the universal covering space that transforms according to some complex character of the fundamental group. Equivalently it is a section of a certain line bundle on the Riemann surface in the same component as the canonical bundle. Prym differentials were introduced by . The space of Prym differentials on a compact Riemann surface of genus ''g'' has dimension ''g'' – 1, unless the character of the fundamental group is trivial, in which case Prym differentials are the same as ordinary differentials and form a space of dimension ''g''. ==References==
