Abstract
We show that the topological massive BF theories can be written as a
pure BF term through field redefinitions. The fields are rewritten as
power expansion series in the inverse of the mass parameter in. We also
give a cohomological justification of this expansion through BRST
framework. In this approach the BF term can be seen as a topological
generator for massive BF theories. (C) 2002 Elsevier Science B.V. All
