SUMMARY:Algebraic and enumerative combinatorics seminar - Mahrud\nSayrafi-
  Constructing exceptional collections for toric varieties
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n Mahrud Sayrafi\n\nAFFILIATION:\n McMaster University
 \n\nLOCATION:\n MC 5417\n\nABSTRACT:  Exceptional collections are a powe
 rful tool for\nunderstanding the derived category of coherent sheaves on 
 algebraic\nvarieties\, with applications in commutative algebra\, biratio
 nal\ngeometry\, and mirror symmetry. While the existence of exceptional\n
 collections is known for classical varieties such as Grassmannians\nand f
 lag varieties\, constructing explicit collections for toric\nvarieties pr
 esents challenges in combinatorial algebraic geometry. In\nthis talk I wi
 ll describe a computational approach to constructing\nfull strong except
 ional collections consisting of complexes of line\nbundles for toric vari
 eties. No background in derived categories is\nassumed.\n\nTHERE WILL BE 
 A PRE-SEMINAR PRESENTING RELEVANT BACKGROUND AT THE\nBEGINNING GRADUATE L
 EVEL STARTING AT 1:30PM.
