On the diagonalisation of von Neumann regular matrices. (English) Zbl 0596.15012

Let R be any ring, associative with unit element, A an \(m\times n\) matrix over R. Then A is said to be von Neumann regular if there exists X over R such that \(AXA=A\). Rings are studied over which von Neumann regular matrices are diagonalizable.
