TL;DR: In this paper, a rather detailed account is presented of a number of the most elementary aspects of this rapidly growing field, and a detailed account of the main challenges involved in this field is discussed.
Abstract: These lectures do not at all provide a general review of this rapidly growing field. Instead a rather detailed account is presented of a number of the most elementary aspects.

TL;DR: In this paper, a compilation of coupling constants and low-energy parameters are given for pi N, KN, NN, YN, and meson-meson scattering, and a comparison of SU(3) comparison and predictions are discussed.

TL;DR: In this article, the equivalence between the free Fermi theory and a chiral Bose theory with Wess-Zumino action was shown for two-dimensional non-abelian background fields.

TL;DR: In this paper, the holographic correspondence between field theories and string/M theory is discussed, focusing on the relation between compactifications of string theory on anti-de Sitter spaces and conformal field theories.

TL;DR: In this paper, the authors construct the generating functional of U(3)×U(3), which allows them to calculate the Green functions up to and including terms of order p4 (at fixed radio m quark p 2 ) in terms of a few coupling constants which chiral symmetry leaves undetermined.

TL;DR: In this article, the strong interactions of low-lying meson resonances (spin ⩽ 1) with the octet of pseudoscalar mesons ( π, K, η ) are considered to lowest order in the derivative expansion of chiral SU(3).

TL;DR: The idea of dynamical gauge bosons of hidden local symmetries in nonlinear sigma models is reviewed in this article, where it is shown that any nonlinear Sigma model based on the manifold G/H is gauge equivalent to a linear model possessing a Gglobal × Hlocal symmetry, Hlocal being a hidden local symmetry.

TL;DR: In this paper, the expectation value of the Wilson loop in N = 4 supersymmetric Yang-Mills theory is investigated for the two special cases of a circular loop and a pair of antiparallel lines, and it is shown that the sum of an infinite class of ladder-like planar diagrams, when extrapolated to strong coupling, produces an expectation value characteristic of the results of the AdS / CFT correspondence.
