Spectral Theory of Bounded Linear Operators

Focusing on spectral theory for bounded linear operators, this textbook covers essential topics such as the spectral theory and functional calculus for normal operators on Hilbert spaces, the Riesz-Dunford functional calculus for Banach-space operators, and Fredholm theory in both Banach and Hilbert spaces. It provides detailed proofs of all theorems with clarity, particularly for spectral theorems, ensuring students gain a comprehensive understanding of these critical concepts in functional analysis.
