Monday, April 28 at 3:30 in 228 Kerchof Hall Wolfgang Spitzer (UC Davis) "From Atomic Physics to Semi-classical Analysis" ABSTRACT: We review some classical results and recent developments in the mathematical theory of atoms. Starting with the question of the stability of an atom we discuss some properties of the periodic table of elements, such as the size and the ground state energy of an atom as a function of the nuclear charge. This leads to standard semi-classical eigenvalue problems for Schroedinger operators, for which we introduce a new coherent states' calculus. This is part of a joint work with J.P. Solovej." -------------------------------------------------------------------------- Travel plans: Arrive Saturday evening (4/25) from Roanoke by car Sunday evening dinner at Almut's Travel on to Blacksburg on Tuesday.
