Commutativity of rings with constraints on commutators
2000This paper studies commutativity of rings \(R\) satisfying polynomial identities of the form\break \(x^t[x^n,y]y^r=[x,y^m]y^s\) and three similar forms, where \(n,m,r,s,t\) are suitably-chosen nonnegative integers. Whether the theorems are correct as stated is not clear, but for some \((n,m,r,s,t)\) the proofs given do not work.

Commutativity of rings with constraints involving a subset
1993Let \(R\) be a ring. Denote by \(Z(R)\) the center of \(R\), \(N(R)\) the set of nilpotent elements of \(R\), \(A(R)\) a nonempty subset of \(R\), \(\mathbb{Z}[t]\) the ring of polynomials in \(t\) with coefficients in \(\mathbb{Z}\), the ring of integers. As usual, for every \(x\), \(y\) in \(R\), \([x,y] = xy - yx\).
