Fano manifolds with big tangent bundle: a characterisation of $V_5$

Algebraic Geometry 2021-10-15 v1

Abstract

Let X be a Fano manifold with Picard number one such that the tangent bundle T_X is big. If X admits a rational curve with trivial normal bundle, we show that X is isomorphic to the del Pezzo threefold of degree five.
