Algebraic K-theory

K-theory spectrum

In mathematics, given a ring R, the K-theory spectrum of R is an Ω-spectrum whose nth term is given by, writing for the suspension of R, , where "+" means the Quillen's + construction. By definition, . (Wikipedia).

Mike Hill: An introduction to chromatic homotopy theory - Lecture 3

The goal of the minicourse will be to introduce the participants to the subject chromatic homotopy theory. This lecture series will require some familiarity with the stable homotopy category. I will first introduce some of the key players in chromatic homotopy theory, the Morava K-theories
