Fixed Points and Hyers-Ulam-Rassias Stability of Cauchy-Jensen Functional Equations in Banach Algebras
Abstract We prove the Hyers-Ulam-Rassias stability of homomorphisms in real Banach algebras and of generalized derivations on real Banach algebras for the following Cauchy-Jensen functional equations: "Equation missing"<!-- image only, no MathML or LaTex -->, "Equation missing"<!-- image only, no MathML or LaTex -->, which were introduced and investigated by …
