SUMMARY:From total positivity to quantum algebras - Stephane Launois (Kent
 )
DTSTART:20121128T163000Z

UID:TALK40520@talks.cam.ac.uk
CONTACT:Christopher Brookes
DESCRIPTION:In recent publications\, the same combinatorial description ha
 s arisen for three separate objects of interest: non-negative cells in the
  real Grassmannian (Postnikov\, Williams)\; torus orbits of symplectic lea
 ves in the classical Grassmannian (Brown\, Goodearl and Yakimov)\; and tor
 us invariant prime ideals in the quantum Grassmannian (Launois\, Lenagan a
 nd Rigal). The aim of this talk is to present some of these results and ex
 plore the reasons for this coincidence.\n
