Abstract:

In this paper, the Chow groups of projective hypersurfaces are studied. We will prove that if the degree of the hypersurface is sufficiently high, its Chow group is “small” in the sense that its formal tangent space vanishes. Then, we will give an example in which the formal tangent space is infinite dimensional.
