Telescopic red-shift conjecture

Let RR be a commutative ring spectrum with telescopic complexity nn, meaning that the thick subcategory determining its telescopic height is TR=Cn1\mathcal{T}_R=\mathfrak{C}_{n-1}. Here K(R)K(R) denotes the algebraic KK-theory spectrum of RR. Telescopic red-shift conjecture. The spectrum K(R)K(R) is a commutative ring spectrum with telescopic complexity n+1n+1. This is a formulation of the red-shift phenomenon, predicting that algebraic KK-theory raises chromatic complexity by one. The source also mentions the Ausoni–Rognes formulation for suitably finite K(n)K(n)-local commutative ring spectra.
