On The Commutativity of J-Rings
Published online by Cambridge University Press: 20 November 2018
Extract
A ring R is called a J-ring if there exists an integer n > 1 such that xn = x for every x ∈ R. The following beautiful theorem due to Jacobson (4, 5) is a generalization of Wedderburn's theorem, which asserts that every finite division ring must be a field.
