1. It is time for a New Deal for mathematics

   Nestor Guillen · arXiv:2611.04213

   The AI labs' vision is based on extraction (of data, wealth, and political power). Mathematicians must oppose it, moving past personal reflections and towards reforming mathematics' social contract.

1. Derived Equivalences for Terminal Threefold Flops via Local Index-One Covering Models

   Xingbang Hao · arXiv:2611.04844

   Inspired by the quadratic involutions of Corti-Pukhlikov-Reid and Gavin Brown's description of hypersurface flips via toric GIT, we apply similar symmetries to local covering models of terminal threefold flops. We recover the derived equivalence of their canonical stacks by pullback and pushforward along the fibre product over the canonical stack of the contraction target, revisiting the local picture in Kawamata's work.
