An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In mathematics, the Lebesgue constants (depending on a set of nodes and of its size) give an idea of how good the interpolant of a function (at the given nodes) is in comparison with the best polynomial approximation of the function (the degree of the polynomials are fixed). The Lebesgue constant for polynomials of degree at most n and for the set of n + 1 nodes T is generally denoted by Λn(T ). These constants are named after Henri Lebesgue.

Property Value
dbo:abstract
  • En anàlisi numèrica, més concretament en , s'anomena la constant de Lebesgue a un nombre que permet veure si una distribució de nodes és numèricament estable o no. És a dir, actua com a nombre de condició d'aquesta distribució. (ca)
  • En mathématiques, la constante de Lebesgue liée à un ensemble de points donne une idée de la qualité de l'interpolant d'une fonction aux points donnés par rapport à la meilleure approximation polynomiale de cette fonction à degré fixé. Elle est nommée d'après Henri Lebesgue. (fr)
