Convergence of power sequences of B-operators with applications to stability
Sameer Chavan, Zenon Jan Jabłoński, Il Bong Jung +1
The B-operators (abbreviation for Brownian-type operators) are upper triangular 2x2 block matrix operators that satisfy certain algebraic constraints. The purpose of this paper is…

Lifting Brownian-type operators with subnormal entry
Sameer Chavan, Zenon Jan Jablonski, Il Bong Jung +1
In this paper, we study Brownian-type operators, which are upper triangular block matrix operators with entries satisfying some algebraic constraints. We establish a li…
