This lecture covers the concept of unitarity bounds and the operator product expansion in the context of conformal field theory. It delves into topics such as conformal blocks and the conformal bootstrap, providing insights into how to create primary states, the state-operator map, and the projection into the state of energy. The lecture also discusses the fixed coefficients by symmetry, OPE inside 3-point functions, and the importance of all correlation functions of local operators. Furthermore, it explores the calculation of conformal blocks and the conformal bootstrap, emphasizing the significance of crossing symmetry and the determination of scaling dimensions.
