Higher order Lupaş-Kantorovich operators and finite differences

V Gupta - Revista de la Real Academia de Ciencias Exactas …, 2021 - Springer
It is well-known that Lupaş operators are not exponential type operators, although they
preserve linear functions. The differential operator is not applicable to estimate nice …
