A perturbation of m-order derivations on Banach algebras
m-order derivation approximate m-order derivation stability
2010/2/25
Let \A be a unital Banach algebra and let m, 1 \leq m \leq 4, be an integer. If f: \A \to \A is an approximate m-order derivation in the sense of Hyers-Ulam-Rassias, then f: \A \to \A is an exact m-or...
Note on Generalized Jordan Derivations Associate with Hochschild 2-cocycles of Rings
Derivation Jordan derivation generalized derivation generalized Jordan derivation Hochschild 2-cocycle
2010/2/26
We introduce a new type of generalized derivations associate with Hochschild 2-cocycles and prove that every generalized Jordan derivation of this type is a generalized derivation under certain condit...
On Jordan Generalized Higher Derivations in Rings
Higher Derivations Generalized Higher Derivations Commutator
2010/2/26
I. N. Herstein proved that any Jordan derivation on a prime ring of characteristic not 2 is a derivation. M. Breşar extended this result to semiprime rings, while M. Ferrero and C. Haetinger exte...
We define the notion of generalized higher derivations and give some elementary relations between generalized higher derivations and higher derivations in the usual sense. We extend the result of an e...
Lifts of Derivations to the Semitangent Bundle
Vector Field Derivation Complete lift Semitangent bundle
2010/3/1
The main purpose of this paper is to investigate the complete lifts of derivations for semitangent bundle and to discuss relations between these and lifts already known.
Let R be a prime ring. Let s , t be two homomorphisms and d be a (s,t)-derivation of R. The purpose of this paper is to prove two results: (i) If char R \neq 2, U is a non-zero ideal of R, s is subjec...
