Jordan embeddings and linear rank preservers of structural matrix algebras

Ilja GogiÄ, Mateo TomaÅ¡eviÄ

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…

Characterizing Jordan embeddings between block upper-triangular subalgebras via preserving properties

Ilja GogiÄ, Tatjana Petek, Mateo TomaÅ¡eviÄ

Let $M_{n}$ be the algebra of $n \times n$ complex matrices. We consider arbitrary subalgebras $A$ of $M_{n}$ which contain the algebra of all upper-triangular matrices (i.e.…
