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. Web1 Answer Sorted by: 2 Some remarks rather than an answer: A may be only densely defined and unbounded, hence may not be Hilbert-Schmidt. But rather the inverse of A is compact. Moreover, coercivity guaranttes that the inverse of A is bounded, then you apply the H …
