Integrability in Sigma-Models
arXiv:1712.07725
Abstract
This is a write-up of lectures on integrable sigma-models, which covers the following topics: (1) Homogeneous spaces, (2) Classical integrability of sigma-models in two dimensions, (3) Topological terms, (4) Background-field method and beta-function, (5) S-matrix bootstrap in the O(N) model, (6) Supersymmetric cosets and strings on AdS(d)xX.
46 pages, 12 figures, based on lectures at the Les Houches summer school "Integrability: From Statistical Systems To Gauge Theory" (Les Houches, 6.06-1.07. 2016)
