Abstract
This thesis serves as a self-contained review of some recent advances in the study of three-dimensional N=4 quiver gauge theories and their Coulomb branch moduli spaces in particular. Our investigation leverages and develops the Hilbert series and abelianisation approaches and finds them mutually complementary. Their synthe- sis provides an explicit construction of the Coulomb branch with several desirable properties: for example, the global symmetry is made explicit and any complex mass deformation is easily derived. Moreover, it naturally handles two generalisations of quiver gauge theories: non-simply laced quivers and previously unknown wreathed quivers. Many concrete examples are provided to illustrate the concepts.
