Lagrange interpolation and entire functions
For a function f defined almost everywhere on R. Let {Ln (f)} be the sequence of Lagrange interpolation polynomials that approximates f, where the nodes are taken to be the zeros of a certain sequence of orthogonal ...Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de Matemáticas. -
On the rate of convergence of hermite-fejér polynomials to functions of bounded variation on the zeros of certain jacobi polynomials
In this paper, we study the Hermite-Fejér interpolation, Hn(f,x), for a function f of bounded variation on [-1,1] when the inter)olation is taken over the zeros of Jacobi polynomials, Pn (∝,β ) (x) when |∝|, | β| ≤ ½.Our ...Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de Matemáticas.
