Grüss-type and Ostrowski-type inequalities in approximation theory

We discuss the Grass inequalities on spaces of continuous functions defined on a compact metric space. Using the least concave majorant of the modulus of continuity, we obtain a Grass inequality for the functional L(f)=H(f;x), where H:C[a,b]→C[a,b] is a positive linear operator and x∈[a,b] is fixed....
