Heat and resolvent expansions in the noncommutative case
Matthias Lesch (Bonn)
Let M be an oriented connected compact Riemannian 4-manifold. We show that if the sectional curvature satisfies K ≥ 1 and the covariant differential of the curvature tensor satisfies |∇R|∞ ≤ 2/pi, then the intersection form of M is definite.
