  Ordinal number - Wikipedia, the free encyclopedia
Ordinals may be categorized as: zero, successor ordinals, and limit ordinals (of various cofinalities).
Ordinals may be used to label the elements of any given well-ordered set (the smallest element being labeled 0, the one after that 1, the next one 2, "and so on") and to measure the "length" of the whole set by the least ordinal which is not a label for an element of the set.
Any ordinal can be made into a topological space by endowing it with the order topology (since, being well-ordered, an ordinal is in particular totally ordered): in the absence of indication to the contrary, it is always that order topology which is meant when an ordinal is thought of as a topological space.

 Ordinal number   (Site not responding. Last check: 2007-10-22)
Ordinal numbers, or ordinals for short, are numbers used to denote the position in an ordered sequence: first, second, third, fourth, etc. The mathematician Georg Cantor showed in 1897 how to extend this concept beyond the natural numbers to the infinite and how to do arithmetic with these transfinite ordinals.
The size aspect leads to cardinal numbers, which were also discovered by Cantor, while the position aspect is generalized by the ordinal numbers described here.
There are ordinal numbers which can not be reached from ω with a finite number of the arithmetical operations addition, multiplication and exponentiation.

 Ordinal number
Viewed this way, every natural number is a well-ordered set: the set 4 for instance has the elements 0,1,2,3 which are of course ordered as 0<1<2<3 and this is a well-order.
A natural number is smaller than another if and only if it is an element of the other.
The first transfinite ordinal is &omega;, the set of all natural numbers.

 Successor ordinal - Wikipedia, the free encyclopedia
When defining the ordinal numbers, an absolutely fundamental operation that we can perform on them is a successor operation S to get the next higher one.
An ordinal number which is S(β) for some ordinal β is called a successor ordinal.
Ordinals which are neither zero nor successors are called limit ordinals.

Category:Set theory Ordinal numbers, or ordinals for short, are numbers used to denote the position in an ordered sequence: first, second, third, fourth, etc. (See How to name numbers.) In mathematics, ordinal numbers are an extension of the natural numbers to accommodate infinite sequences, introduced by Georg Cantor in 1897.
Arithmetic operations on ordinals can be captured by algorithms that transform Cantor normal forms, similar to, but more complicated than, the algorithms for integer arithmetic in terms of the decimal notation usually taught in primary education.
Ordinals which don't have an immediate predecessor can always be written as a limit of a net of other ordinals (but not necessarily as the limit of a sequence, i.e.

Ordinal numbers are general construed as adjectives followed by (countable) nouns in singular:
Ordinal numbers are generally considered to be ordered from high to low; so that first place is considered highest, and fifth is lower than second.

 Ordinal knowledge: Number names and number concepts in Chinese and English Canadian Journal of Experimental Psychology ...
Ordinal number names are typically learned later than cardinal names, but languages also differ in the regularity with which they form these names.
Elementary school children in China and the U.S. showed differences in the acquisition and use of ordinal numbers corresponding to linguistic differences in ordinal names in their native languages.
These results suggest that (a) children induce their language's set of ordinal number names by generalization based on rules sanctioned by early examples, and (b) the relation between ordinal names and ordinal concepts is a complex one, with language only one source of difficulty in understanding ordinal relations.
