Topological BF theories are analysed by considering a test massive par
ticle subject to the field on an external given background. The equati
ons of motion are solved completely. It is shown that the topological
selection of trajectories is implemented by a topological equation who
se set of solutions is related to the intersection invariant theory of
p and 1-chains on a (p + 1 )-dimensional manifold.
