In this paper we present a sort of Korovkin-type result on asymptotic formulae for sequences of linear operators not necessarily convergent but A-summable, A being a sequence of infinite matrices.

In this paper we present a new result on the saturation of sequences of linear operators in a multivariate and simultaneous setting. Specifically, a small o saturation result is obtained for the partial derivatives of the classical Bernstein bivariate operators on the unit simplex. Solutions of...
