Description

This lecture explores the relation of Ward identities to symmetries, focusing on isometries, conserved currents, and conformal symmetry. It discusses the transformation of operators under symmetries, topological operators, and the constraints imposed by Ward identities on correlators in specific cases. The lecture also covers path integrals, canonical quantization, and the Ising model, emphasizing the importance of conformal symmetry in these contexts.
