Defect Conformal Field Theories describe critical points of Quantum Field Theories excited or modified in the neighbourhood of a large p ‐dimensional submanifold. We elucidate the constraints of conformal invariance on correlation functions and we provide both recurrence relations, and in some cases exact results, for the conformal blocks with scalar external operators.
