It contains 20 papers on the many-body problem and quantum graphs, including many-body localization, random Schr|dinger operators, many-body fermionic systems, atomic systems, effective equations, and applications to quantum field theory, as well as Schr|dinger operators on graphs and general spectral theory of Schr|dinger operators.
The many-body problem is a famous model of Celestial Mechanics proposed first by Newton, many papers were devoted to its investigation and many important results were obtained (see, for example, [17,23]).

In the 1992 edition of his book A Guide to Feynman Diagrams in the Many-Body Problem, physicist Richard Mattuck compares the dilemma to trying to describe a galloping horse and all the grains of dust that it kicks up.
Their study helped them understand that the process by which stem cells differentiate is a many-body problem.
Mathematicians E (Princeton U.) and Lu (New York U.) study the solution to the Kohn-Sham equation in the density functional theory of the quantum many-body problem in the context of the electronic structure of the smoothly deformed macroscopic crystals.
We show in this section that the sine basis can also be effective for the many-body problem. We consider a system of N identical bosons that are bound by attractive pair potentials V([x.sub.i] - [x.sub.j]) in one spatial dimension.
Although the nuclear standoff is becoming a many-body problem, humanity can still arrest widespread proliferation throughout the nations opposed to Enlightenment values.

It seems that a truly rigorous and elegant solution will be achieved only by finding a mathematical transformation that reduces the many-body problem to a one-body problem.
Among the topics are the validity of random matrix theories for many-particle systems, the angular-momentum dependence of the density of states, group theory and the propagation of operator averages, electromagnetic sum rules by spectral distribution methods, compound-nuclear tests of time reversal invariance in the nucleon-nucleon interaction, strength functions and spreading widths of simple shell model configurations, and underlying symmetries of realistic interactions and the nuclear many-body problem.
