In mathematics, the partition topology is a topology that can be induced on any set X by partitioning X into disjoint subsets P; these subsets form the basis for the topology. There are two important examples which have their own names: * The odd–even topology is the topology where and Equivalently, . * The deleted integer topology is defined by letting and . The trivial partitions yield the discrete topology (each point of X is a set in P, so ) or indiscrete topology (the entire set X is in P, so ). Any set X with a partition topology generated by a partition P can be viewed as a pseudometric space with a pseudometric given by: This is not a metric unless P yields the discrete topology. The partition topology provides an important example of the independence of various separation axioms. Unless P is trivial, at least one set in P contains more than one point, and the elements of this set are topologically indistinguishable: the topology does not separate points. Hence X is not a Kolmogorov space, nor a T1 space, a Hausdorff space or an Urysohn space. In a partition topology the complement of every open set is also open, and therefore a set is open if and only if it is closed. Therefore, X is regular, completely regular, normal and completely normal. X/P is the discrete topology. (Wikipedia).

Partitions of a Set | Set Theory
What is a partition of a set? Partitions are very useful in many different areas of mathematics, so it's an important concept to understand. We'll define partitions of sets and give examples in today's lesson! A partition of a set is basically a way of splitting a set completely into disj

I define closed sets, an important notion in topology and analysis. It is defined in terms of limit points, and has a priori nothing to do with open sets. Yet I show the important result that a set is closed if and only if its complement is open. More topology videos can be found on my pla
