On \(\varepsilon\)-derivations and local \(\varepsilon\)-derivations
The authors consider \(\varepsilon\)-derivations and local \(\varepsilon\)-derivations. They describe \(\varepsilon\)-derivations in certain graded algebras by their actions on elements satisfying some special conditions. One of the main results is applied to local \(\varepsilon\)-derivations on some certain graded algebras.
