Abstract This is the paper where the cardinal splines are conceived for the first time for approximating. AuthorsTiberiu Popoviciu (Institutul…

AbstractIn this note we consider a linear and positive compound approximation operator of D.D. Stancu type depending of several parameters.…

AbstractIn the present note, we study a certain Durrmeyer type integral modification of Bernstein polynomials. We investigate simultaneous approximation and…
