## Abstract The present paper introduces a kind of Kantorovich type Shepard operators. Complete results including direct and converse results, equivalence results are established. As Della Vecchia and Mastroianni ([4], [7]) did, our results involve a weighted modulus of smoothness related to step‐f

The polynomials are shown to be dense in weighted Bergman spaces in the unit disk whose weights are superbiharmonic and vanish in an average sense at the boundary. This leads to an alternative proof of the Aleman-Richter-Sundberg Beurling-type theorem for zero-based invariant subspaces in the classi

In this work, for the first time, generalized Faber series for functions in the Bergman space A 2 (G) on finite regions with a quasiconformal boundary are defined, and their convergence on compact subsets of G and with respect to the norm on ), the best approximation to f by polynomials of degree n
