Abstract
The research project is on the characteristic classes and intersection homology theory. The first subject to be investigated concerns Milnor classes. It is curious that, at the moment, there are few (or none) examples and applications of them. Another point on Milnor classes, is that the Prof. Brasselet gave a conjecture formula for duality of these classes in terms of polar varieties. Now, it is expected to explicit the proof of this conjecture. Another part of this project is to provide a geometric representation of cicles permited in intersection homology theory. (AU)
