Pushout Geometry of Galois, Étale, and Null Groupoids

We show that Galois, étale, and null groupoids share the same pushout geometry, yielding a unified local-to-global structure across arithmetic, algebraic, and Lorentzian settings via a common generative nucleus.

Abstract

We show that Galois, étale, and null groupoids share the same pushout geometry, yielding a unified local-to-global structure across arithmetic, algebraic, and Lorentzian settings via a common generative nucleus.
