Abstract
The principal properties of a system of n particles at zero temperature can be deduced from knowledge of the energy E 0 of the ground-state wavefunction Φ 0(x 1 σ 1, ... ,x n σ n )
It is evident that when the particles interact and n is large, solving the eigenvalue equation (4.1) can present considerable difficulty. For this reason, it is useful to examine a variety of approximation techniques. The two most important are perturbation theory and the variational method. The next three chapters are based on the variational method. The following is a brief outline of this method.
