Students learn how to construct new topological spaces from existing ones. Long details: Inheriting a topology on a subset.
While now over 50 years old, it remains a classic example of the mid-century effort to formalize the study of "place" (from the Greek topos ) for undergraduate mathematicians. an introduction to general topology paul e long pdf link
An Introduction to General Topology by Paul E. Long: A Comprehensive Guide Students learn how to construct new topological spaces
General topology—often nicknamed "rubber-sheet geometry"—focuses on properties that remain unchanged (invariant) under continuous deformations like stretching or bending, without tearing. Paul E. Long's approach typical of this era likely covers the following standard pedagogical progression: Maharshi Dayanand University - Rohtak Anœ introduction to general topology - Paul E.
