Hom-unitality and hom-associative structures

GermÃ¡n GarcÃa Butenegro, Abdennour Kitouni, Sergei Silvestrov

We study hom-associative structures on general possibly non-associative algebras focusing on one-sided and two-sided unital algebras. New characterizations and aspects of these str…

Lower and upper bounds of joint $(f, I^´)$ -numerical radius functions

Zameddin I. Ismailov, Sergei Silvestrov, Pembe Ipek Al

In this study, the classical results on the joint numerical radius for $n$ -tuples of Hilbert space operators are extended to the setting of the joint $(f, I^´)$ -numerical radius. New…
