THE SEMINAR

THEORY OF DUALITY

DEPARTMENT OF MATHEMATICAL METHODS IN PHYSICS



On the 8th of January 2015, at 10:15 a.m.

Piotr Waluk (KMMF WFUW)

will give a talk on

"Various ways to positivity"

Abstract
ADM mass proves useful in analysis of asymptotically flat spacetimes, although the study of the notion itself was not devoid of difficulties. A good example here is the question of positive definiteness of this quantity, which had to wait over twenty years for a decisive answer. The talk will consist of a short historical review of main methods used to approach the problem, followed by a presentation of an alternative proof of positive-energy theorem, based on elementary tools of differential geometry only.

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.
