The standard eigenfunctions ϕλ = ei⟨λ, x⟩ on flat tori ℝn/L have L-norms bounded independently of the eigenvalue. In the case of irrational flat tori, it follows that L-normalized eigenfunctions have uniformly bounded L1-norms. Similar bases exist on other flat manifolds. Does this property characterize flat manifolds? We give an affirmative answer for compact Riemannian manifolds with quantum completely integrable Laplacians.
