Waldhausen null-homotopy conjecture for rigid analytic spaces

About 6 years old · traced to

Let TT be an adic ring over Zp\mathbb{Z}_p with a two-sided ideal II such that each T/InT/I^n for ne0n e 0 is finite of order a power of pp. Let XX be a rigid analytic space separated and of finite type over Qp\mathbb{Q}_p, and suppose that Dperf(X♯,T)\mathbb{D}_{\mathrm{perf}}(X_\sharp,T) for ♯=eˊt\sharp=\text{\'et} has a Waldhausen structure and that the Waldhausen exact functor RΓ?(X♯,.)R\Gamma_?(X_\sharp,.), with ?=∅?=\emptyset, is defined.

Waldhausen null-homotopy conjecture. The induced map

KDperf(X♯,T)⟶KDperf(T)\mathbb{K}\mathbb{D}_{\mathrm{perf}}(X_\sharp,T)\longrightarrow \mathbb{K}\mathbb{D}_{\mathrm{perf}}(T)

is homotopic to the zero map.

This predicts a vanishing phenomenon for the KK-theory map induced by derived global sections in the pp-adic setting. The surrounding discussion indicates that the expected proof should use finiteness and cohomological-dimension results, but no proof or resolution is supplied here.
