Abstract Extended objects such as line or surface operators. interfaces or boundaries play an important role in conformal field theory. Here we propose a systematic approach to the relevant conformal blocks which are argued to coincide with the wave functions of an integrable multi-particle Calogero-Sutherland problem. This generalizes a recent observation in [1] and makes extensive m... https://www.ealisboa.com/top-offer-Telemarkskongen-SH-best-find/
