The operators studied are of the following types: Bernstein, Bernstein-Faber, Bernstein-Butzer, q-Bernstein, Bernstein-Stancu, Bernstein-Kantorovich, Favard-Sza?sz-Mirakjan, Baskakov and Bala?zs-Szabados. The second main objective is to provide a study of the approximation and geometric proper 410 0$aSeries on concrete and applicable mathematics ;$vv. 8. 606 $aApproximation theory 606 $aOperator theory 606 $aBernstein polynomials 606 $aConvolutions (Mathematics) 615 0$aApproximation theory. 615 0$aOperator theory. 615 0$aBernstein polynomials. 615 0$aConvolutions (Mathematics) 676 $a511/.4 700 $aGal$b Sorin G.$f1953-$0474332 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911150456803321 996 $aApproximation by complex Bernstein and convolution type operators$94859153 997 $aUNINA
