A **topological space** is a fundamental concept in the field of topology, which is a branch of mathematics that studies properties of space that are preserved under continuous transformations. A topological space is defined as an ordered pair \\( (X, \\tau) \\), where: - \\( X \\) is a set, often called the **underlying set**.
