recommendations! Published in 2020 at "Mathematical Methods in the Applied Sciences"

DOI: 10.1002/mma.6192

Abstract: This paper deals with constructing the modified form of the Post‐Widder operators, which reproduce constant and e2ax for fixed a>0 . We discuss the uniform convergence of the constructed operators with the function f .… read more here.

DOI: 10.1016/j.jfa.2017.06.004

Abstract: Abstract Versions of the principle of local reflexivity which respect given nests of subspaces of a Banach space are established. As an application, some duality and lifting theorems on approximation properties of pairs are extended… read more here.

DOI: 10.3390/axioms12010005

Abstract: We construct the blending-type modified Bernstein–Durrmeyer operators and investigate their approximation properties. First, we derive the Voronovskaya-type asymptotic theorem for this type of operator. Then, the local and global approximation theorems are obtained by using… read more here.
