Kuznetsov's Fano threefold conjecture via K3 categories and enhanced group actions

A Bayer, A Perry - Journal für die reine und angewandte Mathematik …, 2023 - degruyter.com

Stability conditions on Kuznetsov components of Gushel–Mukai threefolds and Serre functor

L Pertusi, E Robinett - Mathematische Nachrichten, 2023 - Wiley Online Library
We show that the stability conditions on the Kuznetsov component of a Gushel–Mukai
threefold, constructed by Bayer, Lahoz, Macrì and Stellari, are preserved by the Serre …
