Abstract
We prove that for every nÃn matrix A over the field Z2 there exists an idempotent matrix E such that (AâE)4=0. This result, strengthening the result of Breaz, CÄlugÄreanu, Danchev and Micu, allows us to construct a nil-clean ring that is not strongly Ï-regular, which answers an open question of Diesl.
