Lie inner ideals are nearly Jordan inner ideals

In this note we extend the Lie inner ideal structure of simple Artinian rings developed by Benkart to centrally closed prime algebra A. New Lie inner ideals (which we call non-standard) occur when making this extension. A necessary and sufficient condition for A to have a non-standard inner ideal is the existence in A of a zero square element which is not von Neumann regular.
