Ramanujan Lecture: Algebraic cycles and cohomology theories

Amalendu Krishna ,Tata Institute of Fundamental Research, Mumbai

The aim of this talk is to show how algebraic cycles can be used to describe other known cohomology theories of smooth schemes. The talk will focus mostly on crystalline cohomology in positive characteristic which is classically defined as a sheaf cohomology. We shall show that this cohomology of smooth schemes can be completely defined using algebraic cycles. This provides a new way of understanding crystalline cohomology.
