The PDF is accompanied by this video

We’d like to keep our videos free of interruptions and sponsors, so that the sole focus is the subject at hand. But in order to do that we need your help.

If you find value in our videos and would like to support our work further, and get very useful info that is unavailable anywhere else, consider purchasing this Full PDF on the Introduction to Topology

This Full PDF is a visually guided introduction to the foundational concepts of topology. It is aimed at helping you develop an intuitive and rigorous understanding of topological spaces. We will look at key topics such as open sets, quotient topologies, and classic constructions like the torus, Möbius strip, Klein bottle, and real projective plane, both from the intuitive point of view and rigor with practice. But most importantly, we will answer the question: “How does the concept of open sets relates to these topological shapes?”. This work will systematically build your understanding, beginning with basic definitions and progressing to more advanced notions involving topological identification via equivalence relations. It follows our DIBEOS METHOD: 1. Intuition, 2. Concrete examples, 3. Rigor, 4. Practice (exercises).

Thank you for supporting our work, it means a lot to us!

In any case, if you don’t have the means, we always have our free videos. Thanks again!
