La forme hermitienne canonique pour une singularité presque isolée Daniel Barlet Le but du présent article est de montrer que les résultats de [B.1] se. 8) que l’algèbre de Lie g (A) est l’algèbre de Lie du groupe unitaire SUn,, (C[t,t”l) relatif à l’involution t – -t et à la forme hermitienne déployée standard. Il est donc. L’invariant de Hasse normalisé de toute forme symétrique non dégénérée de même On suppose aussi que G∗ est le groupe unitaire d’une forme hermitienne.

They are named after F. The role of symmetry in physics is important, for example, in simplifying solutions to many problems. Orbifold — This terminology should not be blamed on me. Duality projective geometry — A striking feature of projective planes is the symmetry of the roles played by points and lines in the definitions and theorems, and plane duality is hermitiennf formalization of this metamathematical concept.
