On the 30th of October 2014, at 10:15 a.m.
Michał Wrochna (CNRS, Institut Fourier, Grenoble)
will give a talk on
"Construction of pure states from characteristic Cauchy data"
Abstract
For the Klein–Gordon equation one formulates a characteristic Cauchy
problem by specifying as initial datum the restriction to a lightcone. I
will demonstrate how such characteristic Cauchy problem (also called
Goursat problem) can be solved in the inside of a cone in a globally
hyperbolic spacetime for data in adapted Sobolev spaces. I will then review
applications in Quantum Field Theory, where one is interested in
constructing solutions with a specific wave front set. (This is joint work with
Christian Gérard)
The seminar takes place on Thursdays from 10:15 a.m. to 12:00
in the room 2.23 of the main building of the Faculty of Physics (the 2nd floor), Pasteur Str. 5,
Warszawa.
