Variations on the Bloch-Ogus Theorem
In the present paper we discuss questions concerning the arithmetic
resolution for etale cohomology. Namely, consider a smooth quasi-projective
variety X over a field k together with the local scheme U at a point x. Let Y
be a smooth proper scheme over U. We prove there is the Gersten-type exact
sequence for etale cohomology with coefficients in a locally constant etale
sheaf F of Z/nZ-modules on Y which has finite stalks and (n,char(k))=1.Comment: Latex 2e, XYPIC, 21 page
Degree formula for connective K-theory
We apply the degree formula for connective -theory to study rational
contractions of algebraic varieties. Examples include rationally connected
varieties and complete intersections.Comment: 14 page
