  2. Continuum limit - Wikipedia

    en.wikipedia.org/wiki/Continuum_limit

    An animated example of a Brownian motion-like random walk on a torus.In the scaling limit, random walk approaches the Wiener process according to Donsker's theorem.. In mathematical physics and mathematics, the continuum limit or scaling limit of a lattice model characterizes its behaviour in the limit as the lattice spacing goes to zero.

  3. List of limits - Wikipedia

    en.wikipedia.org/wiki/List_of_limits

    This is a list of limits for common functions such as elementary functions. In this article, the terms a , b and c are constants with respect to x . Limits for general functions

  4. Limit (category theory) - Wikipedia

    en.wikipedia.org/wiki/Limit_(category_theory)

    A functor G : C → D is said to lift limits for a diagram F : J → C if whenever (L, φ) is a limit of GF there exists a limit (L′, φ′) of F such that G(L′, φ′) = (L, φ). A functor G lifts limits of shape J if it lifts limits for all diagrams of shape J. One can therefore talk about lifting products, equalizers, pullbacks, etc.

  5. Classification of discontinuities - Wikipedia

    en.wikipedia.org/wiki/Classification_of...

    In other words, since the two one-sided limits exist and are equal, the limit of () as approaches exists and is equal to this same value. If the actual value of f ( x 0 ) {\displaystyle f\left(x_{0}\right)} is not equal to L , {\displaystyle L,} then x 0 {\displaystyle x_{0}} is called a removable discontinuity .

  6. Pullback (category theory) - Wikipedia

    en.wikipedia.org/wiki/Pullback_(category_theory)

    Another example of a pullback comes from the theory of fiber bundles: given a bundle map π : E → B and a continuous map f : X → B, the pullback (formed in the category of topological spaces with continuous maps) X × B E is a fiber bundle over X called the pullback bundle. The associated commutative diagram is a morphism of fiber bundles.

    respectively. If these limits exist at p and are equal there, then this can be referred to as the limit of f(x) at p. [7] If the one-sided limits exist at p, but are unequal, then there is no limit at p (i.e., the limit at p does not exist). If either one-sided limit does not exist at p, then the limit at p also does not exist.

  8. Limit (mathematics) - Wikipedia

    "The limit of a n as n approaches infinity equals L" or "The limit as n approaches infinity of a n equals L". The formal definition intuitively means that eventually, all elements of the sequence get arbitrarily close to the limit, since the absolute value | a n − L | is the distance between a n and L. Not every sequence has a limit.

  9. Closed graph theorem - Wikipedia

    en.wikipedia.org/wiki/Closed_graph_theorem

    The graph of the Heaviside function on [,] is not closed, because the function is not continuous. In mathematics , the closed graph theorem may refer to one of several basic results characterizing continuous functions in terms of their graphs .
