Mathematics Colloquium EVENT DETAIL Date:  Tuesday, November 27, 2007 Title:  Classical and quantum Birkhoff canonical forms in one dimension Abstract:  Abstract: In the first part of this talk I'll discuss some inverse spectral results for the one-dimensional Schroedinger operator that go back to the early years of quantum mechanics and also discuss the classical antecedents for these results (which go back to work of Abel in the early nineteenth century.) I will then describe some (very recent) improvements on these results involving classical and quantum Birkhoff canonical forms.
