Topology and geometry are branches of mathematics with applications in fields ranging from physics and chemistry to computer science and economics. This textbook offers a rigorous yet accessible approach to the subject that integrates key concepts while providing a robust toolkit that can serve as a starting point for further specialization in diverse areas. It builds intuition by first exploring metric spaces and identifying which properties are topological鈥攖hat is, unchanged by continuous transformations鈥攁nd goes on to discuss topological spaces, topological manifolds, simplicial complexes, smooth manifolds, and Riemannian manifolds. Richly illustrated to encourage students to think visually, Introduction to Topology and Geometry is an essential introduction for advanced undergraduates and beginning graduate students in mathematics and related disciplines.

• Provides a unified treatment of point-set topology, differential topology, and differential geometry
• Prioritizes a deep understanding of core definitions and concepts
• Includes complete proofs of the inverse and implicit function theorems, Sard鈥檚 theorem, the Whitney embedding theorem, and Gauss鈥檚 Theorema Egregium
• Features exercises at the end of each section and a wealth of figures that illustrate the proofs, definitions, and examples presented in the text
• Adaptable to semester-long and quarter-long courses
