Covers the classification of surfaces using polygonal presentations and homeomorphism.

Explores the construction of Riemann surfaces from equilateral triangles and the dynamics of finite-type maps.

Explores the classification of surfaces based on polygonal presentations and the identification of sides and vertices.

Covers the topology of Riemann surfaces and the concept of triangulation using finitely many triangles.

Discusses the classification of surfaces and their fundamental groups using the Seifert-van Kampen theorem and polygonal presentations.
