  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.
