WebThe eigenfunctions result from the boundary conditions. The generic solution to the differential equation is ψ ( x) = A cos λ x + B sin λ x We then apply the boundary … 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. 4. ^ Davydov 1976, p. 21.
