Abstract

We introduce bivariant K-theory for nonarchimedean bornological algebras over a complete discrete valuation ring VV. This is the universal target for dagger homotopy invariant, matricially stable and excisive functors, similar to bivariant K-theory for locally convex topological C\mathbb{C}-algebras and algebraic bivariant K-theory. When the first variable is the ground algebra VV, we get a version of Weibel's homotopy algebraic K-theory, which we call \textit{stabilised overconvergent analytic K-theory}. The resulting analytic K-theory satisfies dagger homotopy invariance, stability by completed matrix algebras, and excision.
