Abstract
Each polynomial hypergroup on ℕ0 generates a family of generalized translation operators T m on sequence spaces. We introduce the concept of almost convergence for polynomial hypergroups (determined by the operators T m ), extending the notion of almost convergence introduced by Lorentz. Our investigations lead to two theorems characterizing almost convergent sequences on polynomial hypergroups.
