Ghadir Jafari (IPM, Tehran): Null hypersurfaces, gravitational energy and the first law of holographic complexity

Friday 16 Apr 2021, 14:00 → 16:00 Europe/Budapest

online

In this talk, I will review some geometrical aspects of null hypersurfaces in spacetime.  Then  I will discuss some applications of a careful examination of these boundaries. These applications include a new definition for the energy of gravitational field and a general relation for variations in holographic complexity.
