Approximate generalized derivations close to derivations in Lie C*-algebras

Madjid Eshaghi EMAIL logo and Sadegh Abbaszadeh


We apply a fixed point theorem to prove that there exists a unique derivation close to an approximately generalized derivation in Lie C*-algebras. Also, we prove the hyperstability of generalized derivations. In other words, we find some conditions under which an approximately generalized derivation becomes a derivation.
