The Equivalence Theorem of Appoximation for Two-dimensional Baskakov Operators
《Chinese Quarterly Journal of Mathematics》2009年第1期27-34,共8页FENG Guo 
Supported by the Scientific Research Fund of Zhejiang Province Education Depart-ment(200700190); Supported by the Science Technique Planed Item of Taizhou City(063KY08);Supported by Major Scientific Research Fund of Taizhou University(09ZD08)
In this paper, we study the convergence rate of two-dimensional Baakakov operators with Jacobi-weights and the approximation equivalence theorem is obtained, making use of multivariate decompose skills and results of ...

On Weighted Tent Space
《Chinese Quarterly Journal of Mathematics》1992年第2期78-83,共6页李兴民 
In this paper, we introduce the A, weights into the tent space, many important results in the tent space are generalized. Also, new relations between the A, weights and Carleson measures are obtained.
