| Abstract: | Letf∈C0,1], andB
n(f,x) be then-th Bernstein polynomial associated with functionf. In 1967, the limit of iterates forB
n(f,x) was given by Kelisky and Rivlin. After this, Many mathematicians studied and generalized this result. But anyway, all
these discussions are only for univariate case. In this paper, the main contribution is that the limit of iterates for Bernstein
polynomial defined on a triangle is given completely.
