Point-set topology: course

Book

Description

This is an introductory, one semester course on point-set/general topology and its applications. Elementary topology. Topics include topologies, separation axioms, connectedness, compactness, continuity, and metric spaces. It is intended for advanced undergraduate and beginning graduate students.

Prerequisites

• calculus (parts of),
• proofs.
