The discrete two-point space is a simple topological space consisting of exactly two distinct points. Usually, these points are denoted as \\( \\\{a, b\\\} \\). The key feature of this topological space is that every subset of the space is considered an open set. This means the topology on this space can be defined as follows: 1. The empty set \\( \\emptyset \\) is open.
