Webeigenfunction. / ( ˈaɪɡənˌfʌŋkʃən) /. noun. maths physics a function satisfying a differential equation, esp an allowed function for a system in wave mechanics. Collins English … Eigenfunctions can be expressed as column vectors and linear operators can be expressed as matrices, although they may have infinite dimensions. As a result, many of the concepts related to eigenvectors of matrices carry over to the study of eigenfunctions. See more In mathematics, an eigenfunction of a linear operator D defined on some function space is any non-zero function $${\displaystyle f}$$ in that space that, when acted upon by D, is only multiplied by some scaling factor called an See more • Eigenvalues and eigenvectors • Hilbert–Schmidt theorem • Spectral theory of ordinary differential equations See more Citations 1. ^ Davydov 1976, p. 20. 2. ^ Kusse & Westwig 1998, p. 435. 3. ^ Wasserman 2016.

Orthogonality is a property that follows from the self-adjointness of∇2 1.Completeness follows from a more subtle property,that the inverse operator of∇2 1 is compact, a property that would take us too far afield to explore.

WebSpherical harmonics are a set of functions used to represent functions on the surface of the sphere S^2 S 2. They are a higher-dimensional analogy of Fourier series, which form a complete basis for the set of periodic functions of a single variable ( ( functions on the circle S^1). S 1).
