A local to global question for linear functionals

George F. Seelinger, Wenhua Zhao

Let $F$ be an algebraically closed field and let $n \geq 3$ . Consider $V = F^{n}$ with standard basis ${e_{1}, \dots, e_{n}}$ and its dual space $V^*= {\mathrm{Hom}}_{F-{\mathr…

A Family of Maximal Mathieu Subspaces of Matrix Algebras

George F. Seelinger, Wenhua Zhao

Let $F$ be a field. In this note we give a construction for a family of maximal Mathieu subspaces (or Mathieu-Zhao subspaces) of the matrix algebras $M_{n} (F)$ $(n \geq 2)$ . As an appl…

Level Matrices

George Seelinger, Papa Sissokho, Larry Spence +1

Let $n > 1$ and $k > 0$ be fixed integers. A matrix is said to be level if all its column sums are equal. A level matrix with $m$ rows is called reducible if we can delete $j$ rows, $0…
