First eigenvalue of the Laplacian of a geodesic ball and area-based symmetrization of its metric tensor
Gimeno, Vicent; Sarrión-Pedralva, Erik Element (2022)Given a Riemmanian manifold, we provide a new method to compute a sharp upper bound for the first eigenvalue of the Laplacian for the Dirichlet problem on a geodesic ball of radius less than the injectivity radius of the ...
