Introductory Functional Analysis Applications Erwin Kreyszig Solutions Apr 2026

I’m working through Kreyszig’s Introductory Functional Analysis with Applications and I’ve hit a few tricky spots in the problem sets. Does anyone know where I can find reliable solutions (partial or complete) for the exercises?

If anyone has a clean, corrected set of solutions (especially for Chapters 4–8: spectral theory, compact operators, etc.), I’d appreciate a pointer. Thanks in advance!
