Test ideals in mixed characteristic via the p-adic Riemann-Hilbert correspondence
Abstract: We introduced a mixed characteristic test ideal using the p-adic Riemann-Hilbert correspondence of Bhatt-Lurie. We show that, under mild finiteness assumptions, this version of test ideal commutes with localization and can be computed by a single alteration up to small perturbation. This is based on joint work in progress with Bhargav Bhatt, Zsolt Patakfalvi, Karl Schwede, Kevin Tucker, Joe Waldron, and Jakub Witaszek.
