Q1 (25 points) (a) Show that d(m, n) = \m? - ? 1 + 1m2-n-1 defines a metric on the set of natural numbers N. Hint: use the monotonicity of the function 1 1/(1+1) for 1 € [0,00). (b) Does d define a metric on the set of integers Z? Justify your answer. (c) Describe all bounded subsets of (N, d). (d) Determine the largest rı > 0 and the smallest r2 > 0 such that, for all m EN, B°(m, n) = {m} and Bºm, r2) = N. (e) Describe all totally bounded subsets of (N, d). + Drag and drop an image or PDF file or click to browse...
