摘要
In this paper, we first revisit and bring together as a sort of survey, properties of Bernstein polynomials of one variable. Secondly, we extend the results from one variable to several ones, namely-uniform convergence, uniform convergence of the derivatives, order of convergence, monotonicity, fixed sign for thep-th derivative, and deduction of the upper and lower bounds of Bernstein polynomials from those of the corresponding functions.
