Completions of pro-spaces

DC Isaksen - Mathematische Zeitschrift, 2005 - Springer
For every ring R, we present a pair of model structures on the category of pro-spaces. In the
first, the weak equivalences are detected by cohomology with coefficients in R. In the …

The homotopy category of flat modules, and Grothendieck duality

A Neeman - Inventiones mathematicae, 2008 - Springer
Let R be a ring. We prove that the homotopy category K (R-Proj) is always \aleph_1-
