General topology—often referred to as point-set topology—is the study of the inherent properties of spaces that are preserved under continuous deformations, such as stretching, twisting, and crumpling, but not tearing or gluing.

This classic 1971 text is a favorite for those wanting a clear, straightforward path into point-set topology.

Not all topological spaces are created equal. Some have very few open sets, making it impossible to distinguish between distinct points. Long systematically introduces the separation axioms ( or Hausdorff, T3cap T sub 3 T4cap T sub 4

While the goal of general topology is to move beyond distance, connecting abstract topologies back to metric spaces is highly instructional. Long details how any metric (distance formula) naturally induces a topology, and discusses the concept of —determining when an abstract topological space can be given a metric. Why Study Paul E.

The heart of the introduction. Long defines a topology, open sets, closed sets, and the axioms (the empty set and whole space are open; finite intersections and arbitrary unions of open sets are open). He provides numerous examples: the discrete topology, indiscrete topology, finite complement topology, and the usual topology on the real line.

Long's approach transitions systematically from concrete real-number metrics to pure abstraction. The textbook is broadly divided into fundamental topological milestones: An introduction to general topology : Long, Paul E
