Classical Appell polynomials are defined by differential equation A n = nA n−1 , n ∈ N, where n ∈ N is the degree of polynomials A n (x). Now we define Appell polynomials of second kind the polynomials given by ∆A n = nA n−1 , n ∈ N (1) where ∆ is the classical difference operator: ∆f (x) = f (x + 1) − f (x). Well known examples are Bernoulli polynomials of… (More)
