We investigate operators all of which powers have the same trace
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 ...
The algebra of thin measurable operators is directly finite

Bikchentaev Airat Midkhatovich (2023)

Let $\mathcal{M}$ be a semifinite von Neumann algebra on a Hilbert space $\cH$ equipped with a faithful normal semifinite trace $\tau$, $S(\mathcal{M},\tau)$ be the ${}^*$-algebra of all $\tau$-measurable operators. Let ...
