Bianchi-convex sets and a new maximum principle for the Ricci flow

Stine Franziska Beitz

We introduce the new notion of Bianchi-convex sets, a generalization of convex sets of algebraic curvature tensors inspired by the second Bianchi identity. It turns out that Hamilt…

Spectrum of generalized Hodge-Laplace operators on flat tori and round spheres

Stine Franziska Beitz

We consider generalized Hodge-Laplace operators $α d δ + β δ d$ for $α, β > 0$ on $p$ -forms on compact Riemannian manifolds. In the case of flat tori and round spheres of different radi…
