The product of two Hilbert–Schmidt operators has finite trace-class norm; therefore, if A and B are two Hilbert–Schmidt operators, the Hilbert–Schmidt inner product can be defined as The Hilbert–Schmidt operators form a two-sided *-ideal in the Banach algebra of bounded operators on H. They also form a Hilbert space, denoted by BHS(H) or B2(H), which can be shown to be naturally isometrically isomorphic to the tensor product of Hilbert spaces WebOrthonormal bases, Gram-Schmidt process Isometries of Hilbert space 7.

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. WebA theorem established by Gelfand and Raïkov in 1943 also shows that every locally compact group has a complete system of irreducible unitary representations in the sense that, for every element g ≠ e, there exist a Hilbert space and an irreducible unitary representation such that [HIS 49].
