Solution of the ℐ2-radical problem in structural matrix near-rings
Published online by Cambridge University Press: 14 November 2011
Extract
We answer the question, raised in 1989, whether the ℐ2-radical of a structural matrix near-ring can be written as the sum of two nontrivial ideals, one of which is nilpotent, in the affirmative.
