There are more than a way to define the closed set:

  • A set is closed if and only if its complement is opened.
  • A set is closed if it contains every limit or accumulation points, the points contained in the set S instead of themselves.

What are the properties of topology in point-set topology?

In point-set topology, the properties of the set S are:X and ∅ belongs to the set S.The intersection of any subsets belongs to the set S.The union of any subsets belongs to the set S.For instance:Let τ = {X,∅}. Then, it's the topology. We call that the trivial or discrete topology. If the set is indiscrete topology, then it contains infinitely many elements!


Is the set of odd whole numbers for division open or closed?

The set of odd whole numbers is neither open nor closed in the context of standard topology on the real numbers. In topology, a set is considered closed if it contains all its limit points; however, odd whole numbers do not include any even numbers or fractions, which means they do not contain limit points that approach them. Additionally, they are not an open set because there are no neighborhoods around any of the odd whole numbers that entirely consist of odd whole numbers.
