Eigenfunction property

WebMar 18, 2024 · Eigenfunctions of a Hermitian operator are orthogonal if they have different eigenvalues. Because of this theorem, we can identify orthogonal functions easily without having to integrate or conduct an analysis based on symmetry or other considerations. Proof WebApr 10, 2024 · The celebrated Faber–Krahn inequality states that the lowest eigenvalue Λ 1 = Λ 1 (Ω) is minimized by a ball, among all sets of given volume. By the classical isoperimetric inequality, it follows that the ball is the minimizer under the perimeter constraint too. The optimality of the ball extends to repulsive Robin boundary conditions, but ...
