Almost harmonic spinors

Nicolas Ginoux, Jean-François Grosjean

We show that any closed spin manifold not diffeomorphic to the two-sphere admits a sequence of volume-one-Riemannian metrics for which the smallest non-zero Dirac eigenvalue tends…

Hypersurfaces with small extrinsic radius or large $λ_{1}$ in Euclidean spaces

Erwann Aubry, Jean-Francois Grosjean, Julien Roth

We prove that hypersurfaces of $R^{n + 1}$ which are almost extremal for the Reilly inequality on $λ_{1}$ and have $L^{p}$ -bounded mean curvature ( $p > n$ ) are Hausdorff close to a sphere…
