[hep-th] seminar

[Branislav Cvetkovic]

Postovane kolege,

u petak 23. septembra u 11 h na Inatitutu za fiziku, u sali 300, Marko 
Vojinovic ce odrzati seminar
pod naslovom "Poincare 2-group and new action for general relativity". 
Apstrakt vam prosledjujem u prilogu.

                                                                         
          Pozdrav Branislav

Apstrakt: We shall introduce the concept of a 2-group, specifically the 
Poincare 2-group. Then we shall construct the topological BFCG action 
and demonstrate how it can be constrained to give general relativity. A 
short analysis of the equations of motion will be given, as well as the 
extension of the formalism to include matter fields. Finally, we shall 
briefly discuss the procedure of spinfoam quantization of the model.
