Fano varieties with split tangent sheaf

Algebraic Geometry 2026-02-18 v1

Abstract

Let XX be a mildly singular Fano variety such that the tangent sheaf is a direct sum. We show that the direct factors are algebraically integrable, so the infinitesimal decomposition induces a product structure on a quasi-\'etale cover of XX.
