本文给出了φ-ψ-近似代数同态、η-近似代数同态和近似代数同态稳定性的定义,研究了代数同态、约当映射与约当同态之间的关系,解决了复Banach代数间近似代数同态的稳定性问题.
We first give the definitions of φ-ψ-approximate algebra homomorphism, η-approximate algebra homomorphism and the stability of approximate algebra homomorphism. Then we study the relations of algebra homomorphism, Jordan mapping and Jordan homomorphism. Finally, the stability of approximate algebra homomorphisms is solved.
