We study the Reconstruction-of-the-Measure Problem (ROMP) for commuting 2-variable weighted shifts $$W_{(\alpha ,\beta )}$$ , when the initial data are given as the Berger measure of the restriction of $$W_{(\alpha ,\beta )}$$ to a canonical invarian

For sequences α ≡ { α n } n = 0 ∞ of positive real numbers, called weights, we study the weighted shift operators W α having the property of moment infinite divisibility ( MID ); that is, for any p > 0 , the Schur power W α p is subnormal. We

Let $\mathbf{T} \equiv (T_1,\cdots,T_n)$ be a commuting $n$-tuple of operators on a Hilbert space $\mathcal{H}$, and let $T_i \equiv V_i P \; (1 \le i \le n)$ be its canonical joint polar decomposition (i.e., $P:=\sqrt{T_1^*T_1+\cdots+T_n^*T_n}$, $(V

In this paper we show that every inner divisor of the operator-valued coordinate function, $zI_E$, is a Blaschke-Potapov factor. We also introduce a notion of operator-valued "rational" function and then show that $\Delta$ is two-sided inner and rati

We present a new connection between the classical theory of full and truncated moment problems and the theory of partial differential equations, as follows. For the classical heat equation $\partial _t u = {\nu } \Delta u$, with initial data $u_0 \in
