  Net (mathematics) - Wikipedia, the free encyclopedia
In topology and related areas of mathematics a net or Moore-Smith sequence is a generalization of a sequence, intended to unify the various notions of limit and generalize them to arbitrary topological spaces.
Nets generalize this concept by weakening the order relation on the index set to that of a directed set.
This may be useful to guide the intuition since the notion of limit of a net is very similar to that of limit of a sequence, which is widely used in the theory of metric spaces.

This article is about its meaning in topology, where the concept of a net is a generalization of that of a sequence, intended to unify the various notions of limit and generalize them to arbitrary topological spaces.
If φ is a net on X based on directed set D and A is a subset of X, then φ is frequently in A if for every α in D there is a β in D greater than or equal to α so that φ(β) is in A.
In general, a net in a space X can have more that one limit, but if X is a Hausdorff space, the limit of a net, if it exists, is unique.

He wrote extensively on mathematics and developed formulas for the volume and surface area of a sphere, and a way to calculate the circumference of a circle.
Much of the work is of the nature of a textbook based on work by earlier writers, but the completeness of the work made it one of the most influential mathematical works of all time.
He also is responsible for much mathematical notation that is now common, including Σ for summation, e for the base of the natural logarithms, ƒ() for functions, π; for circumference of a circle of diameter 1, and i for √-1.
