5. State whether each of the following statements is true or false, in either case substantiate/
justify.
(a) Let f: Q→Q be a contraction on Q. Then by Banach' s fixed point theorem there is a
unique point x EQ such that f(x) = x.
(b) Let X = {x €R :-1<xs 0 or 0 < x s 1} with the usual metric. Then X is disconnected.
(c) The set X = [3,9] as a subset of R with the discrete metric is disconnected.[03]
(d) Every continuous map on any metric space is an open map.
(e) Every connected metric spaces is compact.
(f) The set B = {(xx) ER2 : x² + y2 < 1} as a subset of R2 with indiscrete metric is
disconnected.
(g) The empty set is path-connected.
(h) The set of natural numbers as a subset of real numbers with the usual metric is
compact.
(i) Let fand g be uniformly continuous on a metric space X into R. Then the pr
g is uniformly continuous on X into R. |
