Gauge field configurations appropriate for the infrared region of QCD is proposed. Using the usual QCD action, confinement is realized as in the London theory of Meissner effect.

The AdS/CFT correspondence is established for the AdS 3 space compactified on a solid torus with the CFT field on the boundary. Correlation functions that correspond to the bulk theory at finite temperature are obtained in the regularization a'la Gubser, Klebanov, and Polyakov. The BTZ black hole solutions in AdS 3 are T-dual to the solution in the AdS 3 space without singularity.

We argue that non-supersymmetric large N QCD compactified on T 2 exhibits properties characteristic of an SL(2, Z) T-duality. The kahler structure on which this SL(2, Z) acts is given by m N + iΛ 2 A, where A is the area of the torus, m is the 't Hooft magnetic flux on the torus, and Λ 2 is the QCD string tension.

We investigate non-Abelian gauge theories within a Wilsonian Renormalisation Group approach. The cut-off term inherent in this approach leads to a modified Ward identity (mWI). It is shown that this mWI is compatible with the flow and that the full effective action satisfies the usual Ward identity (WI). The universal 1-loop β-function is derived within this approach and the extension to the 2-...
