| Abstrakt: | 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 |
