============================== Bar-Ilan Combinatorics Seminar ============================== The next meeting of the seminar this year will take place, IYH, on (when) Tuesday, 25 Marcheshvan (Nov. 6) refreshments at 11:45, talk at 12:00 noon (where) Room 331 (Math Dept Seminar Room), Math and CS Building (216), Bar-Ilan University (who) Avital Frumkin (Tel-Aviv University) will talk about (what) "Asymptotic behavior of Kronekcer coefficients for two Young diagrams in a (k,l)-hook" Abstract: --------- Using representation theory of the general Lie superalgebra of type (k,l), and especially the double commutant theorem of Berele-Regev and Sergeev, we can express approximately the way in which the tensor product of two irreducible representations of the symmetric group, corresponding to diagrams contained in the (k,l)-hook, is reduced. This is a non trivial generalization of the works of Christandel and Mitchison on Young diagrams in the k-strip, about which I first heard from Danny Slutsky. Forthcoming Events ================== * 3 Kislev (Nov. 13) Eli Bagno (Jerusalem College of Technology): "The Excedance of colored permutation groups: recursion, symmetry and excedance sets" * 10 Kislev (Nov. 20) Malka Schaps (Bar-Ilan University): "The combinatorics of spin representations of the symmetric and alternating groups" ************************************************************************* You are all invited !
