Certain Results Involving Gammaoperators

Pointwise simultaneous approximation by left gamma quasi-interpolants

“…[1], [4], [5], [9]]) and references there. In order to obtain much faster convergence rate,quasiinterpolants G (k) n of G n in the sense of Sablonnière [8] are considered in [7] and studied quite well in the subsequent papers (e.g.…”
