This lecture covers the concept of conformal correlation functions, including cross-ratios and their properties under permutations. It also delves into the application of conformal transformations, the conformal algebra, dilatations, and the generators P, M, D, and K. The lecture further explores correlation functions of primary operators, scaling dimensions, spinning operators, OPE coefficients, and the stress tensor in the context of Weyl symmetry and conformal Ward identities.
