  • Prompt

    Assess graduate-level understanding of spectral properties of compact operators on Hilbert spaces, including the structure of the point spectrum and accumulation at 0, eigenvalue multiplicities, Riesz–Schauder theory and Fredholm alternatives, and approximation by finite-rank operators (norm/strong approximation and singular value decay). Expect proofs, examples, and counterexamples.
