NettetLim sup and lim inf. – Serlo. By limes superior and limes inferior, mathematicians denote the largest and the smallest accumulation point of a sequence. They are useful, if there are multiple limits and intuitively say what the "greatest limit" (limes superior) and the "smallest limit" (limes inferior) of that sequence are. NettetConvergence of measures. In mathematics, more specifically measure theory, there are various notions of the convergence of measures.

NettetFor a bounded sequence, liminf and limsup always exist (see below). It is possible to define liminf and limsup for unbounded sequences if we allow $\infty$ and $-\infty\text{,}$ and we do so later in this section. It is not hard to generalize the following results to include unbounded sequences; however, we first restrict our attention to bounded ones.

AN UPPER-BOUND FOR THE HAUSDORFF DIMENSION OF LIMSUP …

In mathematics, the limit inferior and limit superior of a sequence can be thought of as limiting (that is, eventual and extreme) bounds on the sequence. They can be thought of in a similar fashion for a function (see limit of a function). For a set, they are the infimum and supremum of the set's limit points, respectively. In general, when there are multiple objects around which a sequence, function, … NettetA sequence {an} { a n } is bounded below if there exists a real number M M such that. M ≤an M ≤ a n. for all positive integers n n. A sequence {an} { a n } is a bounded sequence if it is bounded above and bounded below. If a sequence is not bounded, it is an unbounded sequence. For example, the sequence { 1 n} { 1 n } is bounded above ...
