Cohomology in Grothendieck Topologies and
Lower Bounds in Boolean Complexity

This paper is motivated by questions such as P vs. NP and other questions
in Boolean complexity theory. We describe an approach to attacking such
questions with cohomology, and we show that using Grothendieck topologies
and other ideas from the Grothendieck school gives new hope for such an attack.
