Generalized derivations on algebras
(2002) In Preprints in Mathematical Sciences19990101+01:00 Abstract
 In this paper we study (sigma,tau)derivations on algebras from an abstract point of view. After some definitions and examples, we derive Leibniz type formulas and introduce a module structure on spaces of (sigma,tau)derivations. Then we find all (sigma,tau)derivations on unique factorization domains when sigma and tau are different endomorphisms. We also prove necessary equations for sigmaderivations on the quantum plane. Conditions for products and Jacobi type identities for (sigma,tau)derivations on associative algebras are considered. Then follows an investigation of homogeneous (sigma,tau)derivations on the Witt algebra of degree zero. Finally we generalize the Witt algebra to a skewsymmetric algebra of sigmaderivations on a...
