Strong Converse Results for Linking Operators and Convex Functions

We consider a family Bn,ρc of operators which is a link between classical Baskakov operators (for ρ=∞) and their genuine Durrmeyer type modification (for ρ=1). First, we prove that for fixed n,c and a fixed convex function f, Bn,ρcf is decreasing with respect to ρ. We give two proofs, using various...
