Chapter 11 Uniform Continuity - University of Kentucky
Note that if a function is uniformly continuous on S then it is continuous for every point in S By its very de?nition it makes no sense to talk about a function being uniformly continuous at a point Now we can show that the function f(x) = 1/x2 is uniformly continuous on any set of the form [a+?) |

What is the difference between continuous and uniformly
It is obvious that a uniformly continuous function is continuous: if we can nd a which works for all x 0 we can nd one (the same one) which works for any particular x 0 We will see below that there are continuous functions which are not uniformly continuous Example 5 Let S= R and f(x) = 3x+7 Then fis uniformly continuous on S Proof |

Since cwas arbitrary fis continuous everywhere on I The idea of the proof is basically that the you get for uniform continuity works for (regular) continuity at any point c but not vice versa since the you get for regular continuity may depend on the point c |

The Continuous Extension Theorem Suppose f is uniformly continuous on a dense subset B of A Then there is a unique function F continuous on A such that F(b) = f(b) for every b ? B Terminology Whenever a function F : A ? R coincides on a subset B of A with a function f : B ? R we say “F is an extension of f to A ” |
What is the difference between continuity and uniform continuity?
- Continuity of a function is purely a local property, whereas uniform continuity is a global property that applies over the whole space. A uniformly continuous function is continuous, but the converse does not apply. On the open interval (0,1) the functions f (x) = x and g (x) = 1/x are both continuous, but g is not uniformly continuous.
What is an example of a uniformly continuous function?
- There are examples of uniformly continuous functions that are not ? –Hölder continuous for any ?. For instance, the function defined on by f (0) = 0 and by f ( x) = 1 / log ( x) otherwise is continuous, and therefore uniformly continuous by the Heine-Cantor theorem. It does not satisfy a Hölder condition of any order, however.
How do you determine if a function is continuous?
- Continuity itself is a local property of a function—that is, a function f is continuous, or not, at a particular point, and this can be determined by looking only at the values of the function in an (arbitrarily small) neighbourhood of that point.
What is the difference between continuous and uniformly continuous isometry?
- For instance, any isometry (distance-preserving map) between metric spaces is uniformly continuous. Every uniformly continuous function between metric spaces is continuous. Uniform continuity, unlike continuity, relies on the ability to compare the sizes of neighbourhoods of distinct points of a given space.
