Une conjecture CstC_{\rm st} pour la cohomologie à support compact

This paper demonstrates that adjoining pp-adic analogs of logp\log p and log2πi\log 2\pi i to the ring of analytic functions on the Fargues-Fontaine curve eliminates its Galois cohomology in degrees 1\geq 1, thereby enabling the formulation of CdRC_{\rm dR} and CstC_{\rm st}-type conjectures for the compact support cohomology of pp-adic analytic varieties.

Theorem of the heart for Weibel's homotopy KK-theory

This paper establishes the theorem of the heart for Weibel's homotopy KK-theory (KHKH), proving that the realization functor induces an equivalence KH(C)KH(C)KH(\mathcal{C}^{\heartsuit}) \simeq KH(\mathcal{C}) for small stable \infty-categories with bounded tt-structures, a result derived from a strengthened version of Barwick's theorem that provides precise isomorphism ranges for classical KK-theory and demonstrates the sharpness of these bounds.
