Derivations with Invertible or Nilpotent Values on a Multilinear Polynomial

Derivations with Invertible or Nilpotent Values on a Multilinear Polynomial Let R be a prime ring with no non-zero nil one-sided ideals, d a nonzero derivation on R, and f(X 1,...,X t ) a multilinear polynomial not central-valued on R. Suppose d(f(x 1,...,x t )) is either invertible or nilpotent for all x 1,...,x t in some non-zero ideal of R. Then it is proved that R is either a division ring or the ring of 2 × 2 matrices over a division ring. This theorem is a simultaneous generalization of a number of results proved earlier. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Algebra Colloquium Springer Journals

Abstract

Let R be a prime ring with no non-zero nil one-sided ideals, d a nonzero derivation on R, and f(X 1,...,X t ) a multilinear polynomial not central-valued on R. Suppose d(f(x 1,...,x t )) is either invertible or nilpotent for all x 1,...,x t in some non-zero ideal of R. Then it is proved that R is either a division ring or the ring of 2 × 2 matrices over a division ring. This theorem is a simultaneous generalization of a number of results proved earlier.
