Abstract |
|
Given a distribution of k-planes on a manifold, consider the degeneration locus ΣI consisting of points where the distribution has Lie-bracket growth vector less than or equal I, a fixed integer vector. We calculate the characteristic classes associated to the ΣI for a generic two-plane distribution on a four-manifold. |
