Title: On Locally Nilpotent Derivations Of Fermat Rings
Author: Brumatti P.R.
Veloso M.O.
Abstract: Let Bm n (Fermat ring), where m ≥ 2 and n ≥ 3. In a recent paper D. Fiston and S. Maubach show that for m ≥ n2 - 2n the unique locally nilpotent derivation of Bm n is the zero derivation. In this note we prove that the ring B2 n has non-zero irreducible locally nilpotent derivations, which are explicitly presented, and that its ML-invariant is C. © Journal "Algebra and Discrete Mathematics".
