Abstract
We obtain some Korovkin type theorems for the space \(C(X)\), where \(X\) is a compact metric space (Theorems 2 and 3).
The results are applied to the case when \(X\) is a compact subspace of a prehilbertian space and we obtain bounds for the difference \(\left \Vert B_{n}(f)-f\right \Vert|), where \(Bn\) is the Bernstein-Lototsky-Schnabl operator
