Query: Hamiltonian dynamics: four dimensional BF-like theories with a compact
  dimension   A detailed Dirac's canonical analysis for a topological four dimensional
$BF$-like theory with a compact dimension is developed. By performing the
compactification process we find out the relevant symmetries of the theory,
namely, the full structure of the constraints and the extended action. We show
that the extended Hamiltonian is a linear combination of first class
constraints, which means that the general covariance of the theory is not
affected by the compactification process. Furthermore, in order to carry out
the correct counting of physical degrees of freedom, we show that must be taken
into account reducibility conditions among the first class constraints
associated to the excited KK modes. Moreover, we perform the Hamiltonian
analysis of Maxwell theory written as a $BF$-like theory with a compact
dimension, we analyze the constraints of the theory and we calculate the
fundamental Dirac's brackets, finally the results obtained are compared with
those found in the literature.
