Some Global Direct Estimates for Kantorovitch Polynomials

“…In this connection one may mention some direct estimates in terms of the ordinary (unweighted) first modulus of continuity. Extending an earlier result of Bojanic-Shisha [5], Grundmann [7] showed that…”

Approximation Strategy by Positive Linear Operators

“…which has been studied most widely among the positive linear operators of the form (2) (see [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]). Interested readers could also refer to the related papers for the other similar operators.…”
