Seminarium KMMF "Teoria Dwoistości"

Assigning a "mass" or "energy" value to a gravitational field is asurprisingly difficult task. It is, in fact, still an open problem. Iwill discuss some of the difficulties that arise there and presentrecent results that Jacek Jezierski and I obtained in the linearizedtheory. We hope that insight gained from the approximated model canpoint us in the right direction in the search for a solution of thegeneral problem.Please join our online seminar at Hangouts using the link:meet.google.com/xdd-ejkz-vmw
