Gathering point is actually a concept in topology. It is also called limit point in mathematical analysis. Given a set of fixed points e, for any given δ > 0, there is always an E midpoint in the δ centripetal neighborhood of point P, which is called the aggregation point (or limit point) of P.

Generally speaking, for the gathering point P of point set E on the number axis, we can always find an infinite sequence a(n) (not equal to P) in E, so that Lima (n) = P. For another example, any point inside and on the surface of a sphere in space is the gathering point of the sphere.

Computational aspects of mathematics

Even occupies a dominant position in elementary mathematics. Its position in higher mathematics is also obvious. In addition to many theoretical subjects, advanced mathematics also has a large number of computational subjects, such as differential equations, computational mathematics, statistics and so on. With highly abstract theoretical equipment, it is possible for these disciplines to deal with complex computing problems in modern science and technology.
