The forward difference can be considered as an operator, called the difference operator, which maps the function f to Δh[ f ]. This operator amounts to where Th is the shift operator with step h, defined by Th[ f ](x) = f (x + h), and I is the identity operator. The finite difference of higher orders can be defined in recursive manner as Δ h ≡ Δh(Δ h).

WebFeb 10, 2024 · The forward difference operator Δ: S → S, defined by ( Δ y) n = y n + 1 − y n, satisfies Δ = L − I. The backward difference operator ∇: S → S, defined by ( ∇ y) n = y n − y n − 1, satisfies ∇ = I − R. Since L and R are inverses, we have R Δ = ∇ and L ∇ = Δ. Moreover, I, L, and R commute, so each commutes with Δ and ... WebLet $V$ be the space of all polynomials $f : \\mathbb{N}_{\\ge 0} \\to F$ (where $F$ is a field of characteristic zero).
