On the real Section Conjecture in \'etale homotopy theory

Algebraic Geometry 2025-10-16 v1 Algebraic Topology

Abstract

We study the Section Conjecture in \'etale homotopy theory for varieties over R\mathbb{R}. We prove its pro-22 variant for equivariantly triangulable varieties. Examples include all smooth varieties as well as all (possibly singular) affine/projective varieties. Building on this, we derive the real Section Conjecture in the geometrically \'etale nilpotent (e.g. simply connected) case.
