  Boundedness - Wikipedia, the free encyclopedia
The term bounded appears in different parts of mathematics where a notion of "size" can be given.

 Bounded set - Wikipedia, the free encyclopedia
Therefore, a set is bounded if it is contained in a finite interval.
M is a bounded metric space (or d is a bounded metric) if M is bounded as a subset of itself.

 Metric space - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-12)
In mathematics, a metric space is a set where a notion of distance between elements of the set is defined.
Since the set of the centres of these balls is finite, it has finite diameter, from which it follows (using the triangle inequality) that every totally bounded space is bounded.
a bounded set is referred to as "a finite interval" or "finite region".

From this perspective, a set of people who claim to have some connection to Christ can be shown to be part of the set by ascertaining whether their beliefs and behaviours are within certain set boundaries.
Christendom as a culture was a bounded set, maintained by strict control structures to ensure everyone within its boundaries believed and behaved correctly and by political or military action to defend it against those who did not belong.
The emerging church is incapable of becoming a bounded set, as there is simply (A) too broad of a spectrum in the conversation, and (B) there is no "head office" (including Emergent Village) that is trying to monolithically enforce a set pattern, doctrinal statement, or missional approach.

The subset axiom assures that the set of all of subsets of a bounded set is also a bounded set.
Since every finite set is bounded, this allows us to conclude, as a special case, that the union of any finite number of bounded sets is a bounded set.

Date: 06/24/2003 at 14:57:11 From: Doctor Mike Subject: Re: Proof about a bounded set Hi, The infimum is the LARGEST possible lower bound, and the supremum is the SMALLEST possible upper bound, so it is good to use those words only when you mean exactly those specific concepts.
Assume for notation purposes that the positive "M" is a bound for S. Note, it may NOT be the SMALLEST bound for S. What we are required to prove to show that (b) is true is that S has an upper bound and has a lower bound.
You correctly observed that M must be an upper bound, and -M must be a lower bound.

In mathematics, a metric space is a set (or "space") where a distance between points is defined.
Since the set of the centres of these balls is finite, it has finite diameter, from which it follows(using the triangle inequality) that every totally bounded space is bounded.
A simple way to construct a function separating a point from a closed set (as required for a completely regular space) is to consider the distance between the pointand the set.

 Definition of Upper Bound and Least Upper Bound (Supremum)
S. The set S is said to be "bounded above" by C. A function, f, is said to have a upper bound C if f(x) ≤ C for all x in its domain.
The least upper bound, called the supremum, of a set S, is defined as a quantity M such that no member of the set exceeds M, but if ε is any positive quantity, however small, there is a member that exceeds M - ε.
The least upper bound of a function, f, is defined as a quantity M such that f(x) ≤ M for all x in its domain, but if ε is any positive quantity, however small, there is an x in the domain such that f(x) exceeds M - ε.

 422Notes
If S is a bounded set, show that there is an increasing subsequence of S that converges to sup(S) and a decreasing subsequence of S that converges to inf(S).
This says that the set of distinct points of the sequence is finite and thus no neighborhoods of any point can contain infinitely many distinct points of the sequence.
Further, if a set is bounded and has exactly one cluster point but is not closed, then it does not contain its cluster point.

 About "Bounded Set Theory"   (Site not responding. Last check: 2007-10-12)
Bounded Set Theory (BST) is a weak version of the ordinary set theory.
Its main feature is paying main attention to using bounded quantification (as in the ordinary everyday mathematical practice) and other analogous bounded constructs.
The main universe of sets for BST consists of hereditarily-finite sets and is called HF.

 Remarks on Proving The Fundamental Theorem of Algebra
We first prove the Bounded Value Theorem – the range of a continuous function on a compact set is bounded.
Now proceed by successive bisection: bisect the original compact set (here is where we use the boundedness); on at least one piece, the function is unbounded.
Since the function is bounded, there is a least upper bound, say M, for the range of the function.

To define a regular set, recall that the interior of a set includes all points in the set such that there is a small ball around them which is contained in the set.
The closure of a set includes all points which are the limit of sequences of points in the set.
Finally, a set is semi-algebraic if it can be expressed as a finite union of a finite number of intersections of algebraic half-spaces.

 Analysis WebNotes: Chapter 06, Class 31
Sequentially compact sets are important because continuous functions defined on sequentially compact sets have some very useful properties, which they do not have in general when defined on non-compact sets.
In general the continuous image of closed sets isn't closed, but this example shows that quite often continuous functions on Euclidean space (in particular, on the real line) will map closed set to closed sets.
In Corollary 6.8 we saw that a continuous function defined on a sequentially compact set is always bounded.

 Compactness
The property of being a bounded set in a metric space is not preserved by homeomorphism.
A compact subset of R with its usual metric is closed and bounded.
The closed bounded interval is compact and hence its image is compact and hence is also a closed bounded subset which is in fact an interval also, by connectedness.
