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.
WebHilbert-Schmidt operators on Hilbert spaces are especially simple compact operators. Countable projective limits of Hilbert spaces with transition maps Hilbert-Schmidt … WebHilbert space was found to be very useful for the formu-lations in quantum mechanics (Prugovecki,1982). After the initial works on Hilbert space by Hilbert and Schmidt (Hilbert,1904;Schmidt,1908), James Mercer improved Hilbert’s work and proposed his theorem in 1909 (Mer-cer,1909) which was named the Mercer’s theorem later.
