[hep-th] seminar

[Branislav Cvetkovic]

Postovane kolege,

u petak 2. oktobra u 11 h na Institutu za fiziku, u sali 360,  Marko 
Vojinovic ce odrzati seminar pod naslovom "Hamiltonian analysis of the 
BFCG theory for the Poincare 2-group". Apstrakt vam prosledjujem u 
nastavku.

                                   Pozdrav Branislav



Abstract: We perform the full Hamiltonian analysis of the topological 
BFCG action based on the Poincare 2-group. The Hamiltonian of the theory 
is constructed, and the algebra of constraints is computed. The Dirac 
brackets are evaluated, and the second class constraints are then 
eliminated from the theory. The results are contrasted to those of the 
topological Poincare gauge theory, which is equivalent to the BFCG model 
at the level of the classical action, but has a very different 
Hamiltonian structure. We find a singular canonical transformation 
connecting the two theories.
