We introduce the auxiliary receiver approach as a mathematical tool to write outer bounds in network information theory. This technique yields new outer bounds for basic settings in network information theory such as the relay, interference, and broadcast channel settings. These bounds strictly outperform classical outer bounds at least in some regimes. In this teaching seminar, I take a pedagogical approach and (for the most part) only assume the basic knowledge of a first course in information theory.
