Almost homomorphisms between Banach algebras

초록

It is shown that for an almost algebra homomorphism between Banach algebras, there exists a unique algebra homomorphism near the almost algebra homomorphism. Moreover, we prove that for an almost algebra *-homomorphism between C*-algebras, there exists a unique algebra *-homomorphism near the almost algebra *-homomorphism, and that for an almost al-gebra *-homomorphism between JB*-algebras, there exists a unique algebra *-homomorphism near the almost algebra *-homomorphism
