Titre The second fundamental theorem of invariant theory
Horaire10:30 à 11:30
RésumeThe second fundamental theorem describes all relations among a set of generators of the invariants of an action of a group or Hopf algebra. I shall describe an algebraic geometric approach which, when combined with diagrammatic methods, yields new results in the classical context and also that of the orthosymplectic Lie algebra. This is joint work with R. Zhang, and partly with P. Deligne.
