A polynomial set { P n } n ≥0 is called quasi-monomial if and only if it is possible to define two operators P and M , independent of n , such that P(P n )(x) = nP n -1 ( x ) and M (P n )(x) = P n +1 ( x ). In this paper, we show that every polynomial set is quasi-monomial and we present some useful tools to explicitly express the P and M operators for some polynomial families given by their generating functions. The obtained results are applied to Boas-Buck polynomial sets.
