SUMMARY:Joint Student Colloquium
CLASS:PUBLIC
DESCRIPTION:KANSTANTSIN PASHKOVICH\, COMBINATORICS & OPTIMIZATION\, UNIVERS
 ITY OF\nWATERLOO\n\n\"Four Dimensional Polytopes of Minimum Positive Semid
 efinite Rank\"\n\nFor a given polytope the smallest size of a semidefinite
  extended  \nformulation can be bounded from below by the dimension of th
 e polytope\n \nplus one. This talk is about polytopes for which this boun
 d is tight\,\n \ni.e. polytopes with positive semidefinite (psd) rank equ
 al to their  \ndimension plus one.
