SUMMARY:Algebraic Combinatorics - Li Li
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Bipartite determinantal ideals and concurren
 t vertex maps\n\nSPEAKER:\n Li Li\n\nAFFILIATION:\n Oakland University\n\n
 LOCATION:\n MC 5501\n\nABSTRACT: The classical determinantal ideals play a
 n important role in\ncommutative algebra\, algebraic geometry\, representa
 tion theory and\ncombinatorics. They can be generalized to bipartite deter
 minantal\nideals which are the defining ideals of Nakajima's affine graded
 \nquiver variety. In this talk\, we will introduce a combinatorial model\n
 called concurrent vertex maps to describe the Stanley-Reisner complex\nof 
 the initial ideal of any bipartite determinantal ideal\, and study\nproper
 ties and applications of this model.\n
