On The Absolute Value of Unbounded Operators

Imene Boucif, Souheyb Dehimi, Mohammed Hichem Mortad

The primary purpose of the present paper is to investigate when relations of the types $∣ A B ∣ = ∣ A ∣∣ B ∣$ , $∣ A \pm B ∣ \leq ∣ A ∣ + ∣ B ∣$ , $∣∣ A ∣ - ∣ B ∣∣ \leq ∣ A \pm B ∣$ and $|\overline{\text{Re} A}|…
