SUMMARY:Algebraic and enumerative combinatorics seminar-Leo Jiang
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE:Oriented graded Möbius algebras\n\nSpeaker\n
  Leo Jiang\n\nAffiliation\n University of Toronto\n\nLocation\n MC 5479\n\
 nABSTRACT:The graded Möbius algebra B(M) of a matroid M contains much\nco
 mbinatorial information about the flats of M. Its algebraic\nproperties we
 re instrumental in the proof of the Dowling—Wilson\ntop-heavy conjecture
 . We will introduce a skew-commutative analogue\nOB(M) associated to every
  oriented matroid M\, and discuss its\nalgebraic structure. This is part o
 f ongoing work joint with Yu Li.\n\nTHERE WILL BE A PRE-SEMINAR PRESENTING
  RELEVANT BACKGROUND AT THE\nBEGINNING GRADUATE LEVEL STARTING AT 1:30PM\,
