Intermediate moduli spaces of stable maps
Tập 167 - Trang 47-90 - 2006
We describe the Chow ring with rational coefficients of
$\overline{M}_{0,1}(\mathbb{P}^n,d)$
as the subring of invariants of a ring
$B^*(\overline{M}_{0,1}(\mathbb{P}^n,d);\mathbb{Q})$
, relative to the action of the group of symmetries Sd. We compute
$B^*(\overline{M}_{0,1}(\mathbb{P}^n,d);\mathbb{Q})$
by following a sequence of intermediate spaces for
$\overline{M}_{0,1}(\mathbb{P}^n,d)$
.

The homotopy category of flat modules, and Grothendieck duality
Tập 174 - Trang 255-308 - 2008
Let R be a ring. We prove that the homotopy category K(R-Proj) is always
$\aleph_1$
-compactly generated, and, depending on the ring R, it may or may not be compactly generated. We use this to give a description of K(R-Proj) as a quotient of K(R-Flat). The remarkable fact is that this new description of K(R-Proj) generalizes to non-affine schemes; this will appear in Murfet’s thesis.
