AB  - The first norm characterization of inner product spaces was given by Fréchet in 1935. In 1936, Jordan and von Neumann proved that a normed space X is an inner product space if and only if the parallelogram law holds in X. Since then many other characterizations have been proved. In this talk we study Hyers-Ulam stability for a functional equation on a nonarchimedean normed space. If time permits, a brief digression on nonarchimedean Hilbert spaces will also be presented.
