Residue Formulae for Secondary Characteristic Classes
For a codimension $q$ foliation $Ï$ and a vector field $X$ which preserves $Ï$, we can define the residues of residual secondary characteristic classes as the cohomology classes of the singular set of $X$. We calculate the residues for the examples which are generalizations of those given by Heitsch([He2]).
