The rings which are Boolean. II. (English) Zbl 1276.16034
Summary: We answer the following question: if one has a ring \(R\) of characteristic 2 satisfying \(x^p=x\), for some \(p\); which values of \(p\) imply the identity \(x^2=x\)?
For part I see I. Chajda and F. Švrček [Discuss. Math., Gen. Algebra Appl. 31, No. 2, 175-184 (2011; Zbl 1262.06005)].
