"On the rigid and the de Rham cycle classes"

Let V=Spec(R) and R be a complete discrete valuation ring of mixed
characteris (0,p). For any flat R-scheme X the de Rham fundamental
class of the generic fiber is compatible with the rigid fundamental
class of the special fiber. This is the key result of a joint work
with B. Chiarellotto and A. Ciccioni. I will sketch the proof and give
some applications.
