The Distance from a Rank $n - 1$ Projection to the Nilpotent Operators on $C^{n}$

Zachary Cramer

Building on MacDonald's formula for the distance from a rank-one projection to the set of nilpotents in $M_{n} (C)$ , we prove that the distance from a rank $n - 1$ pro…

Matrix Algebras with a Certain Compression Property II

Zachary Cramer

A subalgebra $A$ of $M_{n} (C)$ is said to be projection compressible if $P A P$ is an algebra for all orthogonal projections $P\in\mathbb{M}_n(\ma…

Matrix Algebras with a Certain Compression Property I

Zachary Cramer, Laurent W. Marcoux, Heydar Radjavi

An algebra $A$ of $n \times n$ complex matrices is said to be \textit{idempotent compressible} if $E A E$ is an algebra for all idempotents $E\in\mathbb{M}_n(\math…
