Seminars for the week of April 16, 2007

Colloquium

Thursday, 3:20, in VinH 16

Professor Willard Miller
of University of Minnesota, Math Department
will speak on
"Second order superintegrable systems and algebraic varieties"

A classical (or quantum) superintegrable systemis an integrable Hamiltonian system on an n-dimensional Riemannian space with potential that admits $2n-1$ functionally independent constants of the motion polynomial in the momenta, the maximum number possible. If the constants are quadratic the system is second order superintegrable. The Kepler-Coulomb system is the best known example. Such systems have remarkable properties: multi-integrability and multi-separability, an algebra of higher order symmetries whose representation theory yields spectral information about the Schrodinger operator, deep connections with special functions and with quasi-exactly solvable systems. I will survey the structure results for systems in 2 and 3 dimensions, and show that in real and complex Euclidean spaces the classification problem reduces to finding points on an algebraic variety.
