: The essential "alphabet" of topology, covering cartesian products, relations, and functions.
: It begins with the fundamental language of set theory—relations and functions—which are essential prerequisites for higher math.
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.
Paul E. Long’s 1971 textbook, "An Introduction to General Topology," provides an accessible, classical approach to point-set topology suitable for undergraduates. The text covers essential topics including axiomatic foundations, topological spaces, and continuous functions, featuring ample exercises for skill development.
