Nil-quasi-clean companion matrices
Let \(R\) be a ring with identity. An element \(e\) in \(R\) is called a quasi-idempotent element if \(e^2=ke\) for some central unit \(k\) in \(R\). For an element \(b\) in \(R\), if there is a positive integer \(m\) such that \(b^m=0\), then \(b\) is called a nilpotent element of \(R\). An elemen...
