DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Vinberg/4/">
 Special Vinberg cones and their application to Supergravity</a>\nby Dmitry
  Alekseevsky (IITP RAS\, Moscow\, Russia) as part of The Vinberg Lecture S
 eries\n\n\nAbstract\nIn the early 1960s\, Vinberg gave a description of ho
 mogeneous convex cones as cones of Hermitian positive definite matrices in
  a matrix $T$-algebra $M_n$ of $(n\\times n)$-matrices whose diagonal entr
 ies are just real numbers\, but off-diagonal elements belong to different 
 vector spaces. It turns out that rank 3 special Vinberg cones (correspondi
 ng to Clifford algebras) have important applications to Supergravity. No s
 pecial background is required. The talk is based on joint works with V. Co
 rtes\; and with A. Marrani and A. Spiro.\n
