Introduction to Algebraic Topology: From Polygons to Surfaces
Starting from foundational topological concepts, explore manifolds, group theory, and the fundamental group, progressing to core algebraic topology tools such as the Seifert–van Kampen theorem, and culminating in a 5-page expository paper and presentation on a chosen topic.

- Sessions 5–6 | Group Theory & Structure: Groups, free products, cosets, homomorphisms, quotient groups, and classification of finitely generated abelian groups
- Sessions 7–8 | The Fundamental Group: Homotopy of paths and computing fundamental groups of manifolds and gluing spaces
- Sessions 9–10 | Van Kampen Theorem & Applications: Degree of maps, retractions, fundamental group of wedges of circles, and induced homomorphisms
- Sessions 11–12 | Independent Topic & Presentation: Deep dive into a chosen topic, short oral presentation, and a ~5-page expository paper
Advanced Directions (tailored by mentor): Preparation for entry-level mathematical research problems in algebraic topology and manifolds
