In this paper we characterize the Blowing-up maps of ordinary singularities for which there exists a natural Gysin morphism, i.e. a bivariant class θ∈ HomD(Y)(Rπ∗QX, QY) , compatible with pullback and with restriction to the complement of the singularity.

Abstract
In this paper we characterize the Blowing-up maps of ordinary singularities for which there exists a natural Gysin morphism, i.e. a bivariant class θ∈ HomD(Y)(Rπ∗QX, QY) , compatible with pullback and with restriction to the complement of the singularity.File in questo prodotto:
