Thom polynomials for singularities of maps
Toru Ohmoto
This is a gentle introduction to a general theory of universal polynomials associated to classification of map-germs, called Thom polynomials. The theory was originated by René Tho…
Universal polynomials for multi-singularity loci of maps
Toru Ohmoto
In the present paper, we prove the existence of universal polynomials which express multi-singularity loci classes of prescribed types for proper morphisms between smooth schemes o…
Unstability problem of real analytic maps
Karim Bekka, Satoshi Koike, Toru Ohmoto +2
As well-known, the stability of proper maps is characterized by the infinitesimal stability. In the present paper we study the counterpart in real…
Equivariant Chern classes of singular algebraic varieties with group actions
Toru Ohmoto
We define the equivariant Chern-Schwartz-MacPherson class of a possibly singular algebraic variety with a group action over the complex number field (or a field of characteristic 0…
