Web1 de mar. de 2024 · Thus orthogonal Cauchy equation is not equivalent to the classic Cauchy equation on the whole inner product space. This phenomenon may show the significance of study of orthogonal Cauchy equation. In the recent decades, stability of functional equations have been investigated by many mathematicians (see [19]). WebFunctional equations are useful to understand the "symmetries" of a given function, pretty much as periodicity. For example, they may be used in the continuation of functions to the complex plane.
