Spectral Theory of Bounded Linear Operators

Carlos Kubrusly is Emeritus Professor at Catholic University of Rio de Janeiro. His research focuses on operator theory, particularly on weak and strong dynamics of Hilbert-space operators and their connection with the Invariant Subspace Problem. He has published over 100 scientific articles in international journals, five books, and served as the editor-in-chief of the journal Computational and Applied Mathematics.

“The exposition of this book is clear and structured. … A rich bibliography comprising 114 entries is provided. The book is addressed to graduate researchers interested in the spectral theory for bounded linear operators.” (Bilel Krichen, zbMATH 1454.47001, 2021)
