Annotation The article states and constructs the proof of a theorem giving a value estimate of kLn(f, x) − f(x)k for f ∈ W3HαM , with Ln belonging to the particular case of S6 (by P. P. Korovkin). The interpolation method is used for the estimate derivation. There is a description of it in the works of Yu. G. Abakumov, O. N. Shestakova and Ye. P. Galaida.
Key words linear operators, interpolation method, approximation estimate.
