Title: A Darboux theorem for Hamiltonian systems in infinite dimensions
Speaker: Professor Ezra Getzler
Speaker Info: Northwestern University (and RIMS)
The Hamiltonian systems we discuss are those of Dubrovin and Novikov, defined on any flat manifold. We show that any formal deformation of the Hamiltonian structure has a normal form of a simple type.Date: Tuesday, March 14, 2000
These results have applications to the deformation theory of completely integrable hierarchies.
