|TITLE:||Putting a Match to Square Ice|
|SPEAKER:||Georgia Benkart (University of Wisconsin-Madison)|
|DATE:||Vendredi, 24 Mars 2006|
Patches of square ice with boundary conditions are in bijection with alternating sign matrices, which in turn have many beautiful connections with domino tilings, tableaux, determinants, group characters, symmetric functions and a whole lot more. This talk will be a tour through these topics.
About the speaker Georgia Benkart received her Ph.D. from Yale University with a thesis written under the supervision of Nathan Jacobson. Since 1974 she has been at the University of Wisconsin-Madison, where she is presently E.B. Van Vleck Professor of Mathematics. She has held visiting positions at the Institute for Advanced Study and the Mathematical Sciences Research Institute. She was the Polya Lecturer of the MAA (2000-2002).
Georgia Benkart's main research area is Lie algebras. She has made fundamental contributions to the structure theory as well as the representation theory of Lie algebras, in particular infinite dimensional Lie algebras. She has also worked in related areas, like quantum groups, combinatorics and associative and nonassociative algebras. She has written over 100 papers and two AMS Memoirs, and is presently working on a book on Combinatorial Representation Theory.
