Chern numbers for singular varieties and elliptic homology.
Chern numbers of a Kupka component
We will consider codimension one holomorphic foliations represented by sections , and having a compact Kupka component . We show that the Chern classes of the tangent bundle of behave like Chern classes of a complete intersection 0 and, as a corollary we prove that is a complete intersection in some cases.

Chern rank of complex bundle
Motivated by the work of A. C. Naolekar and A. S. Thakur (2014) we introduce notions of upper chern rank and even cup length of a finite connected CW-complex and prove that upper chern rank is a homotopy invariant. It turns out that determination of upper chern rank of a space sometimes helps to detect whether a generator of the top cohomology group can be realized as Euler class for some real (orientable) vector bundle over or not. For a closed connected -dimensional complex manifold we obtain...

Circle bundles, adiabatic limits of -invariants and Rokhlin congruences
We present a direct analytic treatment of the Rokhlin congruence formula R2 by calculating the adiabatic limit of -invariants of Dirac operators on circle bundles. Extensions to higher dimensions are obtained.
Classes caractéristiques exotiques et -connexité des espaces de connexions
Le but de ce travail est double : d’une part, généraliser la construction des classes exotiques pour l’appliquer à d’autres problèmes...
Classes caractéristiques pour les cônes projectifs et homologie d'intersection.
Classes caractéristiques réelles de certains G-fibrés vectorials et résidus.
This work is a contribution to study residues of real characteristic classes of vector bundles on which act compact Lie groups. By using the Cech-De Rham complex, the realisation of the usual Thom isomorphism permites us to illustrate localisation techniques of some topological invariants.
