Extremal metrics for Laplace eigenvalues in perturbed conformal classes on products

Differential Geometry 2019-09-09 v2 Analysis of PDEs

Abstract

In this short note, we prove that conformal classes which are small perturbations of a product conformal class on a product with a standard sphere admit a metric extremal for some Laplace eigenvalue. As part of the arguments we obtain perturbed harmonic maps with constant density.
