Exponentials of Normal Operators and Commutativity of Operators: A New Approach
Mohammed Hichem Mortad
We present a new approach to the question of when the commutativity of operator exponentials implies that of the operators. This is proved in the setting of bounded normal operator…

The Sum of Two Unbounded Linear Operators: Closedness, Self-adjointness and Normality
Mohammed Hichem Mortad
In the present paper we give results on the closedness and the self-adjointness of the sum of two unbounded operators. We present a new approach to these fundamental questions in o…
