中文摘要:给出二维广义的Bernsteln多项式的定义,并研究该多项式一致收敛的充分必要条件,用连续模估计该多项式对连续函数的逼近误差.
外文摘要:This paper gives the definition of two-dimensional generalization of the Bernstein Polynomials. We find a sufficient and necessary condition for uniform convergence by the polynomials. By using the modulus of continuity, we estimate the error of approximation for the polynomials to the continuous function.
