K-theory, Algebraic Cycles and Motivic Homotopy Theory Workshop

Date: 13 - 17 June 2022

Location: Isaac Newton Institute for Mathematical Sciences

The programme will focus on the areas of Algebraic K-theory, Algebraic Cycles and Motivic Homotopy Theory. These are fields at the heart of studying algebraic varieties from a cohomological point of view, which have applications to several other fields like Arithmetic Geometry, Hodge theory and Mathematical Physics.

It was in the 1960s that Grothendieck first observed that the various cohomology theories for algebraic varieties shared common properties, which led him to explain the underlying kinship of such cohomology theories in terms of a universal motivic cohomology theory of algebraic varieties. The theory of Algebraic Cycles, Higher Algebraic K-theory, and Motivic Homotopy Theory are modern versions of Grothendieck’s legacy. In recent years it has seen some spectacular developments, on which we want to build further.

The programme will also specifically explore the connections between the following areas:

• Algebraic K-theory, Motivic Cohomology, and Motivic Homotopy Theory;
• Hodge theory, Periods, Regulators, and Arithmetic Geometry;
• Mathematical Physics.

Professor Phillip Griffiths (IAS and Miami) will give the Clay Lecture at this event.
