Deformation of involution and multiplication in a C*-algebra

H. Najafi, M. S. Moslehian

We investigate the deformation of involution and multiplication in a unital $C^{*}$ -algebra when its norm is fixed. Our main result is to present all multiplications and involutions…

On the binary relation $\leq_{u}$ on self-adjoint Hilbert space operators

M. S. Moslehian, S. M. S. Nabavi Sales, H. Najafi

Given self-adjoint operators $A, B \in B (H)$ it is said $A \leq_{u} B$ whenever $A \leq U^{*} B U$ for some unitary operator $U$ . We show that $A \leq_{u} B$ if and only if $f…
