Title: Canonical structure of the 2-BF theory for the Poincare 2-group
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. The canonical transformation which maps between 
the two theories turns out to be singular in a certain sense.
