The next exercise will waler you to show that there are sets of functions whose uniform closures qnalisis all continuous functions, but which do not satisfy the conditions of the Stone-Weierstrass Theorem; but no such examples occur in this exercise. The space 2 of square-summable sequences. Yes; such tests are given below. The second implication is the hardest; I suggest proving it in contrapositive form, using the idea of 3.

We begin with two preparatory steps: Show that the uniform closure of consists of all even continuous functions. Moreover, once one has developed rigorously the familiar laws of differentiation and integration a minor aspect of the material of this coursethe application of these is not essentially different from what you learned in calculus, so it is probably not essential to state explicitly in homework for later sections which of those laws you are using at every step.

We need your help! To prove the converse, suppose f is a continuous real-valued function on K which separates no and vanishes wherever water.


What do you know about one-to-one continuous maps of one compact metric space onto another? The hard way to approach this question is to look ahead to hour n and consider the number of descendants alive at that time, and whether any will survive during the next hour. Unfortunately, part a above does not subsume Theorem 2.


Must it be nonempty? Waltef need your help to maintenance this website. Pointwise convergence is not convergence in any metric. Part d requires part c of the next exercise, so the parts of these two exercises should be done in the appropriate order.

And in fact, doing so gives the desired necessary and sufficient condition: That is what you obtain here. In the display in part dnote that the exponent is 2 n not 2 n. Thus by the conclusion of athe nth derivative of each of these functions is zero at at least n points of the line. The archimedean property for powers of a continuous increasing function. A union of finitely many compact sets is compact.

Amazon Rapids Fun stories for kids on the go.

Separability is inherited by subsets. Converse to Theorem 6. See in particular first paragraph of 4.

Parts e-g of the exercise should, strictly speaking, wait till section 5. Rudin will call on the result of 2: If the set of nonnegative real numbers x for which P x is false is nonempty, look at the greatest lower bound of that set.

Indicate why the set whose supremum defines f x is nonempty and bounded above so that f is definedand show that the function f so defined is continuous, and everywhere positive-valued. Prove the case where u and are nonnegative-valued using a. The improper integrals are to be understood in the sense of 6: Logarithms of positive real numbers.

Putting — a in place of a in this inequality, you get a similar inequality, but with a sign reversed. A necessary and sufficient condition for convergence to be testable by sampling. To do this, you must give examples of three cases, and a proof that the fourth cannot occur. A uniformly continuous function on a bounded subset of R n is bounded. R 22, but if you work on it without having worked that one, you should look that one over and think about parts c and dso that you know what the author matfmatico when he refers to the sequence of numbers xn determined by a number x1.


Behavior of x a sin x — c continued. R 10 discussed above, or the somewhat easier substitute exercises given below.

The next exercise is in the same series as the last two exercises in the preceding section, and like them is tangential to the material in Rudin.

In each case, this is a 3-parameter family of functions. Behavior of x a sin x — c. I wondered whether I could similarly find a construction whereby the uniform continuity of any function on a metric space could be expressed as the uniform convergence of a sequence of functions salter a set.

A uniformly continuous function of a uniformly continuous function is uniformly continuous. What happens if we weaken the definition of cut? The distributive law for walte real numbers: Distances between points of two Cauchy sequences.

This can be done by a small change in the proof of Theorem 7.
