Explore the intricate connections between branes and quivers in string theory through this comprehensive lecture. Delve into the fundamental concepts, including the three types of approaches and the nine spatial dimensions involved in brane systems. Learn how to translate brane setups into quivers, examining blue branes, green branes, and semi-infinite green branes. Investigate brain creation, the Coulomb branch, and the process of translating N=4 quivers into standard quivers. Analyze various examples, study HK quotients, and understand the moduli space Higgs branch. Conclude with a Q&A session to clarify any remaining questions on this complex topic in theoretical physics.
