Commutators in $C*$-algebras and traces

Bikchentaev Airat Midkhatovich (2023)

Let $\mathcal{H}$ be a Hilbert space, $\dim \mathcal{H}= +\infty$. Let $X=U|X|$ be the polar decomposition of an operator $X\in \mathcal{B}(\mathcal{H})$. Then $X$ is a non-commutator if and only if both $U$ and ...
Differences and commutators of idempotents in C*-algebras

Bikchentaev Airat Midkhatovich; Fawwaz Khattab Omar (2021)

We establish similarity between some tripotents and idempotents on a Hilbert space $H$ and obtain new results on differences and commutators of idempotents $P$ and $Q$. In the unital case, the difference $P - Q$ is associated ...
Ideal spaces of measurable operators affiliated to a semifinite von Neumann algebra

Bikchentaev Airat Midkhatovich (2018)

We investigate ideal spaces of measurable operators affiliated to a semifinite von Neumann algebra
