Laplace-Beltrami operator — In differential geometry, the Laplace operator can be generalized to operate on functions defined on surfaces, or more generally on Riemannian and pseudo Riemannian manifolds. This more general operator goes by the name Laplace Beltrami operator … Wikipedia
Normal operator — In mathematics, especially functional analysis, a normal operator on a complex Hilbert space H (or equivalently in a C* algebra) is a continuous linear operator that commutes with its hermitian adjoint N*: Normal operators are important because… … Wikipedia
Almost Mathieu operator — In mathematical physics, the almost Mathieu operator arises in the study of the quantum Hall effect. It is given by: [H^{lambda,alpha} omega u] (n) = u(n+1) + u(n 1) + 2 lambda cos(2pi (omega + nalpha)) u(n), , acting as a self adjoint operator… … Wikipedia
