Extra talk The stable homotopy groups of spheres can be thought of as a derived analogue of the integers, and

they encode deep information about algebraic and differential topology as well as arithmetic geometry.

Chromatic homotopy theory reveals this hidden information and provides a systematic approach to

the computation of these groups.

After a quick survey of the chromatic perspective, we explain recent joint work with Schlank and

Stapleton which implies that the chromatic approach is asymptotically algebraic. Our work is based

on a categorical generalization of ideas from mathematical logic which should be of interest beyond the

applications to stable homotopy theory.
