Property Value
dbo:abstract
  • Der Begriff des Witt-Rings stammt aus der Algebra. Er soll die quadratischen Räume über einem Ring , d. h. die -Moduln mit symmetrischer Bilinearform, zusammenfassen. Er wurde 1937 von Ernst Witt eingeführt. (de)
  • En mathématiques, un groupe de Witt sur un corps commutatif, nommé d'après Ernst Witt, est un groupe abélien dont les éléments sont représentés par des formes bilinéaires symétriques sur ce corps. (fr)
