Gauge symmetries play a crucial role in modern theoretical physics. They lead to the known fundamental interactions and provide methods to construct consistent novel interacting theories. These symmetries, however, imply redundancies in our description of physical systems, which complicate the quantization procedure of these theories. In this seminar I plan to give an overview of different methods that can be used to deal with these symmetries. More precisely, I will give a very brief introduction to the Becchi-Rouet-Stora-Tyutin (BRST) gauge fixing and the Batalin-Vilkovisky (BV) formalism, and illustrate how these methods work with simple explicit examples.
