Abstract

Motivated by Scholze and Fargues’ geometrization of the local Langlands correspondence using perfectoid diamonds and Clausen and Scholze’s work on the K-theory of adic spaces using condensed mathematics, we introduce the Efimov K-theory of diamonds. We propose a pro-diamond, a large stable (infinity,1)-category of diamonds D^{diamond}, diamond spectra and chromatic tower, and a localization sequence for diamond spectra.
