摘要:

In this article, we prove, both in complete non-Archimedean normed spaces and in 2-Banach spaces, the generalized Hyers-Ulam stability of an equation characterizing multi-quadratic mappings. Our results generalize some known outcomes.

关键词: Multi-quadratic mapping, (generalized) Hyers-Ulam stability, the Jordana-von Neumann functional equation, direct method
