SUMMARY:Tutte Colloquium -Oliver Pechenik-Dynamics of Increasing Tableaux
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n Oliver Pechenik\n\nAFFILIATION:\n University of Wate
 rloo\n\nLOCATION:\n MC 5501\n\nABSTRACT: Standard tableaux are certain gr
 ids of numbers that lead a\ndouble life in algebraic combinatorics\, with 
 distinct roles in\ngeometry and in representation theory. Extending the ge
 ometry to\nK-theory led to a corresponding extension of the combinatorics 
 to a\ntheory of increasing tableaux. I will discuss a long and ongoing\npr
 ogram to explicate the combinatorial dynamics of these tableaux\,\nwhich s
 eems to be revealing that they also have a mysterious second\nlife in repr
 esentation theory. Despite the algebraic connections\, the\ncore problem i
 s fundamentally combinatorial: to give a sufficiently\ngood bijection betw
 een tableaux and a set of planar diagrams.
