SUMMARY:Algebraic and enumerative combinatorics seminar-Leo Jiang
CLASS:PUBLIC
DESCRIPTION:TITLE:Oriented graded Möbius algebras\n\nSpeaker\n Leo Jiang\n
 \nAffiliation\n University of Toronto\n\nLocation\n MC 5479\n\nABSTRACT:Th
 e graded Möbius algebra B(M) of a matroid M contains much\ncombinatorial 
 information about the flats of M. Its algebraic\nproperties were instrumen
 tal in the proof of the Dowling—Wilson\ntop-heavy conjecture. We will in
 troduce a skew-commutative analogue\nOB(M) associated to every oriented ma
 troid M\, and discuss its\nalgebraic structure. This is part of ongoing wo
 rk joint with Yu Li.\n\nTHERE WILL BE A PRE-SEMINAR PRESENTING RELEVANT BA
 CKGROUND AT THE\nBEGINNING GRADUATE LEVEL STARTING AT 1:30PM\,
