Compactly supported continuous function is uniformly ...

    $\begingroup$ Actually this can be answered easily if it is true that a sequence of uniformly continuous functions that converge uniformly to a continuous function, then that function necessarily uniformly continuous. $\endgroup$ – Chris Cave Feb 10 '15 at 11:52

    continuity is the same. This means that a continuous function defined on a closed and bounded subset of Rn is always uniformly continuous. Proposition 2.1.2 Assume that X and Y are metric spaces. If X is com-pact, all continuous functions f : X → Y are uniformly continuous. Proof: We argue contrapositively: Assume that f is not uniformly continu-

    Definition 4: A function of topological spaces is continuous if for every open subset of , is an open subset of X. Definition 5: An open rectangle is defined to be a subset of of the form , i.e. There are real numbers and where for all i and In the case of ,...

Uniform continuity - Wikipedia

    https://en.wikipedia.org/wiki/Uniform_continuity
    The Heine–Cantor theorem asserts that every continuous function on a compact set is uniformly continuous. In particular, if a function is continuous on a closed bounded interval of the real line, it is uniformly continuous on that interval.

    sequentially compact metric spaces are equivalently compact metric spaces. compact spaces equivalently have converging subnet of every net. sequentially compact metric spaces are totally bounded. continuous metric space valued function on compact metric space is uniformly continuous. paracompact Hausdorff spaces are normal

Continuity and Uniform Continuity

    https://www.math.wisc.edu/~robbin/521dir/cont.pdf
    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. Choose ">0.

    Continuity and Uniform Continuity Below I stands for any one of the intervals (a;b), [a;b), (a;b], [a;b], (a;1), [a;1), (1;b), (1 ;b], (1 ;1) = R. Let fbe a function de ned on an interval I. De nition of Continuity on an Interval: The function f is continuous on Iif it is continuous at every cin I. So,

    • (a) If f, g are continuous functions with compact support, then they are bounded and uniformly continuous, since the functions are zero outside a compact (i.e. closed, bounded) interval, and a continuous function on a compact interval is bounded and uniformly continuous.

    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 …
