SUMMARY:London analysis seminar: Dean Baskin (TAMU) — Propagation of sing
ularities for the Dirac—Coulomb system
CLASS:PUBLIC
DESCRIPTION:Propagation of singularities for the Dirac—Coulomb system\nTh
e Dirac equation describes the relativistic evolution of electrons and pos
itrons. We consider the (time-dependent!) Dirac equation in three dimensio
ns coupled to a potential with Coulomb-type singularities. Motivated by a
question from quantum field theory\, we prove a propagation of singulariti
es result for this equation and show that singularities are diffracted by
the singularities of the potential. If time permits\, I will describe how
similar techniques can be used to characterize the asymptotic behavior of
solutions of this system. This talk is based on joint work with Jared Wuns
ch as well as work with Bob Booth and Jesse Gell-Redman.\nZoom link\nLondo
