LEBESGUE (H.) — Le mathématicien Henri Lebesgue est l’un des fondateurs de l’analyse moderne. Presque tous ses travaux se rattachent à la théorie des fonctions de variables réelles. Sa conception de l’intégration et de la mesure renouvelle l’étude des problèmes… … Encyclopédie Universelle
Lebesgue covering dimension — or topological dimension is one of several inequivalent notions of assigning a topological invariant dimension to a given topological space. Contents 1 Definition 2 Examples 3 Properties 4 … Wikipedia
Lebesgue-Stieltjes integration — In measure theoretic analysis and related branches of mathematics, Lebesgue Stieltjes integration generalizes Riemann Stieltjes and Lebesgue integration, preserving the many advantages of the latter in a more general measure theoretic framework.… … Wikipedia
Lebesgue's density theorem — In mathematics, Lebesgue s density theorem states that for any Lebesgue measurable set A, the density of A is 1 at almost every point in A. Intuitively, this means that the edge of A, the set of points in A whose neighborhood is partially in A… … Wikipedia
Lebesgue point — In mathematics, given a Lebesgue integrable function f, a point x in the domain of f is a Lebesgue point if:lim {r ightarrow 0^+}frac{1}int {B(x,r)} !|f(y) f(x)|,dy=0.Here, B(x,r) is the ball centered at x with radius r, and |B(x,r)| is the… … Wikipedia
Point process — In statistics and probability theory, a point process is a type of random process for which any one realisation consists of a set of isolated points either in time or geographical space, or in even more general spaces. For example, the occurrence … Wikipedia
Lebesgue spine — In mathematics, in the area of potential theory, a Lebesgue spine or Lebesgue thorn is a type of set used for discussing solutions to the Dirichlet problem and related problems of potential theory. The Lebesgue spine was introduced in 1912 by… … Wikipedia
