| Summary: | This paper aims to two-dimensional extension of some univariate
positive approximation processes expressed by series. To be easier
to use, we also modify this extension into finite sums. With respect to these
two new classes designed, we investigate their approximation properties in
polynomial weighted spaces. The rate of convergence is established, and
special cases of our construction are highlighted. |
