An extension of Petek-Šemrl preserver theorems for Jordan embeddings of structural matrix algebras

Ilja Gogić, Mateo Tomašević

Let $M_{n}$ be the algebra of $n \times n$ complex matrices and $T_{n} \subseteq M_{n}$ the corresponding upper-triangular subalgebra. In their influential work, Petek and Šemr…

Jordan embeddings and linear rank preservers of structural matrix algebras

Ilja Gogić, Mateo Tomašević

We consider subalgebras $A$ of the algebra $M_{n}$ of $n \times n$ complex matrices that contain all diagonal matrices, known in the literature as the structural matrix alg…
