On [epsilon]-derivations and local [epsilon]-derivationsFošner, Ajda (Avtor) Fošner, Maja (Avtor) mathematicsalgebragraded algebrasgraded prime algebrasgraded semiprime algebras▫$\epsilon$▫-derivationslocal ▫$\epsilon$▫-derivationsIn this paper, we describe ▫$\epsilon$▫-derivations in certain graded algebras by their actions on elements satisfying some special conditions. One of the main results is applied to local ▫$\epsilon$▫-derivations on some certain graded algebras.20102013-10-15 12:07:05Delo ni kategorizirano2353sl
