Webgroup of Dperf(X) as the Grothendieck group of the p-th subquotient of the filtration. We then obtain a definition of the codimension-p Chow group of Dperf(X) by analogy with Quillen’s coniveau spectral sequence (see [Qui73, §7]). We prove: Theorem (3.2.6). Let X be a non-singular, separated scheme of finite type over a field. Endow Dperf(X) WebFor the codimension 2 Chow group of Godeaux-Serre varieties, we can prove a strong relation to the codimension 2 Chow group of BG. The outline of the paper is as follows. In section 1, we de ne the Chow ... scheme of nite type over k.) For any variety X, let CHiX denote the group of i-dimensional algebraic cycles on X modulo rational ...

Perhaps the first example of a theorem in intersection theory is Bézout’s theorem, which tells us that two projective plane curves C and D, of degrees c and d and which have no components in common, meet in at most cd points. Furthermore if one counts the …
