Récent 43+ Indiscrete Topology Example. Recall from the topological spaces page that a set $x$ and a collection $\tau$ of subsets of $x we will now look at two rather trivial topologies known as the discrete topologies and the indiscrete. The power set p(x) of a non empty set x is called the discrete topology on x, and the space (x,p(x)) is. To see this, take an arbitrary countably infinite subset $y$ of $x$. I find the example confusing.

If every infinite subset of $x$ is declared open, then this topology is the discrete topology, not the indiscrete one.

It has an empty subbasis. Other articles where discrete topology is discussed: It has a basis comprising only the whole space. Mohammed hichem mortad university of oran, algeria. Discrete space — in topology, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points are isolated from each other in a certain sense. In topology, a topological space with the trivial topology is one where the only open sets are the every indiscrete space is a pseudometric space in which the distance between any two points is zero. The only closed subsets are the whole space and the empty subset. Network topologies describe the methods in which all the elements of a network are mapped.
