Limit of distributions
In mathematics, specifically in the theory of generalized functions, the limit of a sequence of distributions is the distribution that sequence approaches.The distance, suitably quantified, to the limiting distribution can be made arbitrarily small by selecting a distribution sufficiently far along the sequence.The notion is a part of distributional calculus, a generalized form of calculus that is based on the notion of distributions, as opposed to classical calculus, which is based on the narrower concept of functions.is the distribution given by for each test function, provided that distribution exists., the limit of the sequence of numbersexists and that (2) the linear functionaldefined by the above formula is continuous with respect to the topology on the space of test functions.More generally, as with functions, one can also consider a limit of a family of distributions.Consider, for example, the function: Since, by integration by parts, we have:denote the distributional limit ofbe the rectangle with positive orientation, with an integer N.
