Abstract: In this paper, we study the convergence rate of two-dimensional Baskakov operators with Jacobi-weights and the approximation equivalence theorem is obtained, making use of multivariate decompose skills and results of one-dimensional Baskakov operators.

Key words:  Baskakov operators, Jacobi-weights, multivariate decompose, equivalence theorem
