Abstract: |
In this talk, we discuss operators that are represented by upper triangular 2 × 2 block matrices whose entries satisfy some algebraic constraints. We call them Brownian-type operators. These operators emerged from the study of Brownian isometries studied by Agler and Stankus via detailed analysis of the time shift operator of the modified Brownian motion process. We address the issue of subnormality of Brownian-type operators and relate it to a spectral inclusion of a pair of commuting normal operators. This talk is based on a joint work with Z. J. Jablonski, I. B. Jung and J. Stochel. |
