In mathematical analysis, the Hilbert–Schmidt theorem, also known as the eigenfunction expansion theorem, is a fundamental result concerning compact, self-adjoint operators on Hilbert spaces. In the theory of partial differential equations, it is very useful in solving elliptic boundary value problems. WebHilbert-Schmidt operators 7. Spectral Theorem for self-adjoint compact operators Appendix: topologies on nite-dimensional spaces Among all linear operators on Hilbert spaces, the compact ones (de ned below) are the simplest, and most closely imitate nite-dimensional operator theory. In addition, compact operators are important in practice.
