27.04.2011. :: Seminar grupe za cestice i gravitaciju

U sredu 27. aprila na Institutu za fiziku, u sali 300, u 11 h, Marko Vojinovic ce odrzati seminar pod naslovom "Introduction to Loop Quantum Gravity (3/3)". U prilogu je apstrakt seminara na engleskom jeziku.

Abstract:
This is the third seminar in the 3-lecture course on Loop Quantum Gravity. We shall demonstrate the basics of the covariant nonperturbative quantization of the gravitational field, i.e. the spinfoam formalism. The relationship between general relativity and the topological BF theory will be established, and we shall define the discretized path integral for the BF theory. This will then be modified to accommodate for the simplicity constraints which reduce BF theory to general relativity. The lectures are mainly intended for graduate students, so the technical level will not be high and should be suitable for everyone interested.
