Lee, Sang-Hyuk; Park, Choonkil Hyers-Ulam-Rassias stability of isometric homomorphisms in quasi-Banach algebras. (English) Zbl 1144.39025 J. Comput. Anal. Appl. 10, No. 1, 39-51 (2008). The authors prove the Hyers-Ulam-Rassias stability of isometric homomorphisms in quasi-Banach algebras, related to the Cauchy and Jensen functional equations. They also study isometric isomorphisms between quasi-Banach algebras.
