Lattice gauge theories and the AdS/CFT correspondence

This review is devoted to a comparison between lattice gauge theories and A dS/CFT results for the nonperturbative behavior of nonsupersymmetric Yang-M ills theories. It is intended for readers who are assumed not to be experts in LGT. For this reason the first part is devoted to a pedagogical introdu ction to the Lattice regularization of QCD. In the second part we discuss s ome basic features of the AdS/CFT correspondence and compare the results ob tained in the nonsupersymmetric limit with those obtained on the lattice. W e discuss in particular the behavior of the string tension and of the glueb all spectrum.
