On a conjecture of Stolz in the toric case

Differential Geometry 2024-10-29 v2 Geometric Topology

Abstract

In 1996 Stolz conjectured that a string manifold with positive Ricci curvature has vanishing Witten genus. Here we prove this conjecture for toric string Fano manifolds and for string torus manifolds admitting invariant metrics of non-negative sectional curvature.
