Fock spaces serve as a fundamental framework in both mathematical analysis and quantum theory, providing a rich setting for the study of entire functions equipped with Gaussian weights. In operator ...

For his pioneering development of a mathematical theory that has enabled solutions for previously intractable problems, UC Santa Barbara’s Igor Mezić has received the biennial J. D. Crawford Prize ...

Journal of Operator Theory, Vol. 58, No. 2 (Fall 2007), pp. 415-440 (26 pages) In this paper the well-known result that a definitizable operator in a Krein space remains definitizable after a finite ...

In this paper we characterize when the product of two block Hankel operators on the vector-valued Hardy space is a Hankel operator. We also describe when a block Toeplitz and a block Hankel operator ...
