A Direct Proof for an Eigenvalue Problem by Counting Lagrangian Submanifolds
We focus on one of the Schrödinger operators called the Bochner– Laplacian. Using Jensen’s Formula and Vandermonde convolution, we show directly that for each k = 0, 1, 2, . . . , the number of Lagrangian submanifolds which satisfy the Maslov quantization condition is just equal to the multiplicity of the kth eigenvalue of the operator.
