Abstract
We establish an asymptotic formula for a general sequence of positive linear operators of discrete type. This class represents a generalization in q-Calculus of the operators introduced by C. Mastroianni, the construciton taking its origin in a paper of Baskakov. We also mark out Voronovskaja-type formulae for two particular cases which are q-extensions of the Szasz-Mirakjan operator and the ordinary Baskakov operator.
