SUMMARY:Fixed point properties in Banach spaces - Cornelia Drutu Badea (Un
 iversity of Oxford)

UID:TALK236245@talks.cam.ac.uk
DESCRIPTION:Spectral gap properties can usually be reformulated in terms o
 f fixed point properties for isometric actions or\, equivalently\, in term
 s of contracting properties of Markov operators. One can try to assess the
  `strength' of these properties using the latter two reformulations.\nThe 
 talk shall overview various attempts to do this\, within the setting of un
 iformly convex Banach spaces. This talk is on joint work with John Mackay\
 , Ashot Minasyan and Mikael de la Salle.&nbsp\;
