We review the holographic correspondence between field theories and string/M theory,
focusing on the relation between compactifications of string/M theory on Anti-de Sitter …

Within the theory of Quantum Chromodynamics (QCD), the rich structure of hadrons can be
quantitatively characterized, among others, using a basis of universal nonperturbative …

We suggest a means of obtaining certain Green's functions in 3+ 1-dimensional N= 4
supersymmetric Yang-Mills theory with a large number of colors via non-critical string theory …

We study the renormalization properties of the Wilson loops containing cusp singularities. In
particular, we calculate the two-loop contribution to the cusp anomalous dimension Γ cusp …

We define a new representation for quantum general relativity, in which exact solutions of
the quantum constraints may be obtained. The representation is constructed by means of a …

It is pointed out that the factorization of disconnected Wilson loop amplitudes implies a major
reduction in the dynamical degrees of freedom in the large-N limit of lattice gauge theory; the …

The AdS-CFT correspondence suggests that the Wilson loop of the large N gauge theory
with N= 4 supersymmetry in four dimensions is described by a minimal surface in AdS 5× S …

This paper discusses the sense in which the large N limits of various quantum theories are
equivalent to classical limits. A general method for finding classical limits in arbitrary …

Most of the physical laws are only approximate. The P and T symmetries are broken, the
neutrino has mass, the proton is expected to decay etc. The new discoveries usually reveal …

The aim of the book is to give an introduction to the method of QCD Spectral Sum Rules and
to review its developments. After some general introductory remarks, Chiral Symmetry, the …
