摘要：At what frequencies does the product of two Laplace-Beltrami eigenfunctions on a manifold concentrate? Equivalently, given three eigenfunctions, how large is the integral of their product over the manifold? In this talk, we provide a relatively complete answer to this question, and in the process reveal how the size of these triple products is determined, in an average sense, by the measure of the configurations of triangles in Euclidean space with the three frequencies of the eigenfunctions as side lengths.
