Abstract

Let VV be a complete discrete valuation ring with residue field F\mathbb{F}. We define a cyclic homology theory for algebras over F\mathbb{F}, by lifting them to free algebras over VV, which we enlarge to tube algebras and complete suitably. We show that this theory may be computed using any pro-dagger algebra lifting of an F\mathbb{F}-algebra. We show that our theory is polynomially homotopy invariant, excisive, and matricially stable.
