Symplectic Dynamics Seminar

Riemannian Exponential Map on the Group of Volume-Preserving Diffeomorphisms
Gerard Misiolek
4:00pm|S-101

In 1966 V. Arnold showed how solutions of the Euler equations of hydrodynamics can be viewed as geodesics in the group of volume-preserving diffeomorphisms. This provided a motivation to study the geometry of this group equipped with the $L^2$...

On the Comparison of Trace Formulas
Jim Arthur
2:15pm|S-101

We shall recall the spectral terms from the trace formula for G and its stabilaization, as well as corresponding terms from the twisted trace formula for GL(N). We shall then discuss aspects of the proof of the theorems stated in the first talk that...

Classification of Representations
Jim Arthur
1:00pm|S-101

Suppose that G is a connected, quasisplit, orthogonal or symplectic group over a field F of characteristic 0. We shall describe a classification of the irreducible representations of G(F) if F is local, and the automorphic representations of G in...
