Uniform Convergence Uniform convergence is a stronger version of convergence. To discuss pointwise convergence f n!f, you need to have a sequence of functions ff ng, not just one function. Uniform convergence describes how f n(x) changes when you change n(but don’t change x). f n!fmeans tha if nis large enough, then f n(x) is close to f(x

For any function f: X→R, we define kfk sup:= sup{|f(x)|: x∈X}. Let (f n) n∈Nbe a sequence of functions in X→Rand that we have another function f: X→R. We then make the following two definitions. •We say that (f n) n∈N converges uniformly to f if for every ε 0, there exists N such that kf n −fk Therefore, uniform convergence implies pointwise convergence. But the con-verse is false as we can see from the following counter-example. Example 9. Let {f n} be the sequence of functions on (0, ∞) defined by f n(x) = nx 1+n 2x. This function converges pointwise to zero.

M-test … where a n ⁢ (z) is analytic for all n ≥ 1, and the convergence of the product is uniform in any compact subset of D. … 4 Uniform convergence In the last few sections we have seen several functions which have been defined via series or integrals. We now want to develop tools that will allow us to show that these functions are analytic. Recall that in general, it is not enough to know that the sum f(x) = lim n→∞ f n(x) converges everywhere and that each f or uniform convergence results for smooth functions on T: Theorem: [Z], p.240. (Bernstein) If f2Lip (T) for some > 1 2;then S. N. f!f absolutely as N!1: This theorem is sharp; i.e. there exists f 2Lip.

To prove the same with respect to the second component, we form the difference of its values for two values of t 0, say t Abel's uniform convergence test. Abel's uniform convergence test is a criterion for the uniform convergence of a series of functions or an improper integration of functions dependent on parameters. It is related to Abel's test for the convergence of an ordinary series of real numbers, and the proof relies on the same technique of summation by parts. The test is as follows.

The convergence of the infinite product is uniform if the sequence of partial products converges uniformly. M-test … where a n ⁢ (z) is analytic for all n ≥ 1, and the convergence of the product is uniform in any compact subset of D. …

f n!fpointwise means that for each x2X, if nis large enough, then f n(x) is close to f(x). The de nition reads: 8x2X;8 >0;9N2N such that n N implies d(f n(x);f(x)) < . Uniform Convergence Uniform convergence is a stronger version of convergence. To discuss pointwise convergence f In uniform convergence, one is given \(ε > 0\) and must find a single \(N\) that works for that particular \(ε\) but also simultaneously (uniformly) for all \(x ∈ S\). Clearly uniform convergence implies pointwise convergence as an \(N\) which works uniformly for all \(x\), works for each individual \(x\) also.

It is a “fractal” construction, first thought of by Weierstrass in the 1880’s. For each n ≥ 0, define f n(x) = inf{|x−k/4n| : k ∈ Z}. To clarify what this means, write d n = 1 The equivalence of uniform convergence and learnability was formally established only in the supervised classification and regression setting. In the more general s etting, the “rightward” implications in the diagram above still hold: finite fat-shattering dimensions, uniform convergence, as well as ERM stability, are indeed while applying uniform convergence – described more concretely as follows. Recall that roughly speaking a uniform convergence bound essentially evaluates the complexity of a hypothesis class (see Definition 3.2).

In the more general s etting, the “rightward” implications in the diagram above still hold: finite fat-shattering dimensions, uniform convergence, as well as ERM stability, are indeed It's important to note that normal convergence is only defined for series, whereas uniform convergence is defined for both series and sequences of functions. Take a series of functions which converges simply towards . The convergence is uniform if where is the -norm: , and is the n-th partial sum. Here is my "On The Fly" video of the difference between pointwise and uniform convergence of a sequence of functions. Uniform convergence means there is an overall speed of convergence. In the above example no matter which speed you consider there will be always a point far outside at which your sequence has slower speed of convergence, that is it doesn't converge uniformly.

Let us consider a sum of the form given in eq. (1) and ask whether the sum is convergent.
