16 Graduate Seminar
Graduate Seminar Speaker: Letitia Banu (Western) "Toric varieties associated with a Fan" Time: 15:30 - 16:30 Room: MC 108 Given a fan , we associate to it a variety in the following way: we take the disjoint union of all affine toric varieties corresponding to the cones of the fan and then glue them together using the method: for any two cones \sigma and \tau in the fan, their intersection is a common face of both so that its corresponding toric affine variety is contained in both X_\sigma and X_tau as a principal open subvariety. Now glue X_{\sigma} and X_{\tau} along this common subvariety. The variety obatained in this way is called the toric variety associated with the fan. In the end I will talk about toric varieties associated to a polytope which turn out to be projective toric varieties. |

2 Colloquium
Colloquium Speaker: Megumi Harada (McMaster University) "The topology of Hamiltonian quotients" Time: 15:30 - 16:30 Room: MC 108 Symplectic geometry lies at the crossroads of many exciting areas of research due to its relationship to geometric
representation theory, combinatorics, and algebraic geometry, among others. As often happens in mathematics, the presence of symmetry in these geometric structures -- in this context, a {\em Hamiltonian G-action} for G a Lie group -- turns out to be crucial in the computation of topological invariants, such as the Betti numbers, the cohomology ring, or the K-theory, of symplectic manifolds which arise as {\em Hamiltonian quotients}. I will give a bird's-eye, motivating overview of this subject. Time permitting, I will give a brief survey of my recent work on this topic, which include generalizations of previous work to hyperk\"ahler geometry, as well as to cases in which the symmetry group is the infinite-dimensional loop group LG of a compact Lie group. |
