Random Operators

Course in the fall semester 2010/2011 at TU Chemnitz.

Dates:

Thursdays, 17:15-18:45, Room 41/705

Please send a mail if you want to attend but you cannot because of the time!!

Overview:

Random Operators are used as models for disordered systems in Mathematical Physics. At the same time, their study has widened the scope of operator and spectral theory. The introduction offered in this course will shed light on both aspects.
