Web15 de out. de 2024 · There are cases, depending on the metric space, when many sets are both open and closed. Even more, in every metric space the whole space and the empty set are always both open and closed, because our arguments above did not make use to the metric in any essential way. WebOpen and Closed Sets: Results Theorem Let (X;d) be a metric space. Then 1;and X are both open and closed. 2 The union of an arbitrary (–nite, countable, or uncountable) collection of open sets is open. 3 The intersection of a –nite collection of open sets is open.

WebThe open intervals are open sets of the real line in its standard topology, and form a base of the open sets. An interval is said to be left-closed if it has a minimum element or is left-unbounded, right-closed if it has a maximum or is right unbounded; it is simply closed if it is both left-closed and right closed.

For the second case try Y = ( 0.5, 0.75], X = [ 0, 1] and A = Y.
