Mathematica Bohemica (2017)
  • Ismail Nikoufar
Abstract
In this paper, we consider Lipschitz conditions for tri-quadratic functional equations.
We introduce a new notion similar to that of the left invariant mean and prove that a family of functions with this property can be approximated by tri-quadratic functions via a Lipschitz norm.
Keywords
  • tri-quadratic functional equation,
  • Lipschitz space,
  • stability.
