On the Operator Equations $A^{n} = A^{*} A$

Souheyb Dehimi, Mohammed Hichem Mortad, Zsigmond Tarcsay

Let $n \in N$ and let $A$ be a closed linear operator (everywhere bounded or unbounded). In this paper, we study (among others) equations of the type $A^{*} A = A^{n}$ where $n\geq…

The Fuglede Theorem and Some Intertwining Relations

Ikram Fatima Zohra Bensaid, Souheyb Dehimi, Bent Fuglede +1

In this paper, we show a new and classic version of the celebrated Fuglede Theorem in an unbounded setting. A related counterexample is equally presented. In the second strand of t…
