Basic Algebraic Topology is built on considering objects (such as differential forms) up to boundary (e.g., exterior derivative). However, there is more structure in chains and boundaries that can be extracted by not immediately passing to quotients. We will discuss elementary examples of this, such as the Hopf invariant and Milnor’s higher linking.
