Let p be a prime number, and d: Z ? Z > [0, +?) be a function defined by dp(x, y) = p? max{m?N .. from C. 12. Let (X, d) be a metric space, and let F ? X be a closed subset and K ? X a compact subset of .. Isolated points can cause a problem. 18. Consider Q as a metric space with the usual distance function d(x, y) = |x ? y|, and define. S = {x ? Q : 2 < x2 < 3}. Show that S is closed and bounded in Q, but that S is not compact. Solution. Note that Sc = {x ? Q : x2 < 2 or x2 > 3} since ±. v. 2 /? Q, ±. v. 3 /? Q. Let x ? Sc. Then x2 > 3 or x2 < 2. If x2 > 3 and x > 0 metric in a function space evolved from classical brachistochrone problem of variational calculus. Solution Since | x – y | ? 0 and | x – y | = 0 iff x = y, (d1) follows. .. is also a metric. The new metric spaces {(X, d m. )/m = 1, 2, } are thus obtained from (X, d). Solution: (i) d m. (x, y) = md(x, y) ? 0 ? x, y ? X. Moreover d m. Problem. 1: a) Check if the following spaces are metric spaces: i) X = too:= {(Xn)nEN: Xn E IR for each nand suplxnl < oo}. d(x,y). = sup{lxn-Ynl: n EN}. ii) X = foo, d(x,y). = #{n EN: xn #- Yn} (Hamming distance). iii) Take X to be London. For every pair of points x, y E X, let d(x, y) be the distance that a car needs to drive from x ?. = with at most finitely many nonzero terms .Find a Cauchy sequence in M which does not converge in M ,so that M is not complete.

(3) Show that S is not compact by considering the sequence in lp with kth element the sequence which is all zeros except for a 1 in the kth slot. Note that the main problem is not to get yourself confused about sequences of sequences! Solution 5.13 MAS331: Metric Spaces 2016-17. Solutions to Problems on Chapter 4. 1. (a) Let (x, y) ? R2. Take a sequence (xn,yn) in R2 tending to (x, y). Then, by the d2-version of Prop.2.9, xn > x and yn > y. By the algebra of limits, xnyn > xy, or, in other words, f(xn,yn) > f(x, y). Therefore f is continuous at (x, y), and therefore (since METRIC SPACES. MATH 113 - SPRING 2015. PROBLEM SET #1. Problem 1 (Dis$
