  2. Limit inferior and limit superior - Wikipedia

    en.wikipedia.org/wiki/Limit_inferior_and_limit...

    In mathematical analysis, limit superior and limit inferior are important tools for studying sequences of real numbers.Since the supremum and infimum of an unbounded set of real numbers may not exist (the reals are not a complete lattice), it is convenient to consider sequences in the affinely extended real number system: we add the positive and negative infinities to the real line to give the ...

  3. List of limits - Wikipedia

    en.wikipedia.org/wiki/List_of_limits

    In these limits, the infinitesimal change is often denoted or .If () is differentiable at , (+) = ′ ().This is the definition of the derivative.All differentiation rules can also be reframed as rules involving limits.

  4. Limit (mathematics) - Wikipedia

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

    In mathematics, a limit is the value that a function (or sequence) approaches as the argument (or index) approaches some value. [1] Limits of functions are essential to calculus and mathematical analysis, and are used to define continuity, derivatives, and integrals.

  5. Limit (category theory) - Wikipedia

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

    If the index category J is connected (and nonempty) then the unit of the adjunction is an isomorphism so that lim is a left inverse of Δ. This fails if J is not connected. For example, if J is a discrete category, the components of the unit are the diagonal morphisms δ : N → N J .

  6. Interchange of limiting operations - Wikipedia

    en.wikipedia.org/wiki/Interchange_of_limiting...

    Examples abound, one of the simplest being that for a double sequence a m,n: it is not necessarily the case that the operations of taking the limits as m → ∞ and as n → ∞ can be freely interchanged. [4]

  7. Computation in the limit - Wikipedia

    en.wikipedia.org/wiki/Computation_in_the_limit

    In computability theory, a function is called limit computable if it is the limit of a uniformly computable sequence of functions. The terms computable in the limit, limit recursive and recursively approximable are also used.

  8. Continuous linear operator - Wikipedia

    en.wikipedia.org/wiki/Continuous_linear_operator

    The notion of a "bounded set" for a topological vector space is that of being a von Neumann bounded set.If the space happens to also be a normed space (or a seminormed space) then a subset is von Neumann bounded if and only if it is norm bounded, meaning that ‖ ‖ <.

    Lim was born in 1964 as the eldest son of Lim Chin Teong, a senior civil servant who served as Chief Executive Director of the People's Association (PA) between the late 1970s and early 1980s. His mother, Aw Eng Lian, was a Chinese-language teacher at Zhonghua Girls School for over 40 years.
