Research Abstract

(1) Using motivic Hirzebruch class, we constructed Motive Milnor classe, which is a generalization of the Milnor number. (2) W constructed a zeta function of the motivic Hirzebruch class, a special case of which gives rise to the zeta function of the Chern class. (3) Using the idea in the universal bivariant theory introduced by the representative of this grant, we introduced the notion of fiberwise bordism group and we showed that we could construct a bivariant theory of fiberwise bordism group, using the notion of differentiable spaces. (4) We showed that any additive invariant, which cannot be usually captured as a natural transformation, could be captured as a natural transformation.
