Achievements and Challenges in the Field of Convolution Operators: The Yuri Karlovich Anniversary Volume

Albrecht Böttcher is a professor emeritus at Chemnitz University of Technology. He is known for his work in operator theory, numerical analysis, and matrix analysis, especially for his contributions to Toeplitz operators, matrices, and determinants, and their applications. In 1997, he and Yuri Karlovich

won the Ferran Sunyer i Balaguer Prize for their monograph ``Carleson Curves, Muckenhoupt Weights, and Toeplitz Operators’’.

Oleksiy Karlovych is an associate professor at the NOVA University Lisbon, where he has been working since 2007. His research interests lie at the intersection of operator theory and the theory of function spaces, in particular, in the study of Toeplitz and convolution-type operators on Banach function spaces.

Eugene Shargorodsky is a professor at King’s College London. His research is in operator theory and partial differential equations, in particular, Toeplitz operators, pseudodifferential operators, and spectral theory of Schrödinger operators.

Ilya M. Spitkovsky is a professor emeritus at New York University Abu Dhabi and the College of William and Mary (Williamsburg, Virgina), where he worked in 2013-2024 and 1990-2016, respectively. His research is in operator theory, complex analysis and matrix analysis, in particular, Riemann-Hilbert problems, Wiener-Hopf factorization, spectral theory of Toeplitz operators, and numerical ranges.
