Abstract: "Generalised sheaf cohomology theory", by. J.F. Jardine

This is an expanded version of notes for a set of lectures given at
the Newton Institute during a NATO ASI Workshop entitled ``Homotopy
Theory of Geometric Categories'' on September 23 and 24, 2002. The
paper presents some of the basic features of the homotopy theory of
simplicial presheaves and the stable homotopy theory of presheaves of
spectra, and then displays their use in the course of giving an
outline of proof of Thomason's descent theorem for Bott periodic
K-theory, in the context of equivariant stable categories for
profinite groups.
