Stacks Seminar
Time: 11:30
Speaker: Tom Prince (Western) Title: "Homotopy Theory and Stacks II" Room: MC 108 Abstract: TBA Algebra Seminar
Time: 14:30
Speaker: Ivan Dimitrov (Queen's) Title: "A geometric realization of extreme components of the tensor product of modules over algebraic groups" Room: MC 108 Abstract: In this talk I will explain how the celebrated theorem of Borel-Weil-Bott provides a natural realization of some extreme components of the tensor product of two irreducible modules of simple algebraic groups. I will also discuss a number of connections of our construction with problems coming from Representation Theory, Combinatorics, and Geometry, including questions about the Littlewood-Richardson cone related to Horn's conjecture, settled by Knutson and Tao in the late 1990's. The talk is based on joint work with Mike Roth. |
