In the continuous setting, we expect the product of two oscillating functions to oscillate even more (generically). On a graph G=(V, E), there are only| V| eigenvectors of the Laplacian L= D− A, so one oscillates ‘the most’. The purpose of this short note is to point out an interesting phenomenon: if ϕ 1, ϕ 2 are delocalized eigenvectors of L corresponding to large eigenvalues, then their (pointwise) product ϕ 1⋅ ϕ 2 is smooth (in the sense of small Dirichlet energy): highly oscillatory functions have largely matching oscillation patterns.
