One-Dimensional N-body Problem with 8-Interaction
A. D. Jannussis
Abstract We have studied the one dimensional N-body problem with delta-function interaction and width 2 C. To determine the ground-state energy and the excitation spectrum we arrive at integral equations similar to the equation of Hulthen. The solution of the integral equation is achieved by the moments method and the results are compared with those found in the literature.

Group Theory and the Many Body Problem
M. Moshińsky
Group theoretical techniques are pointed out which are effective for dealing with some many body problems. While Group Theory provides the backbone of all of the following discussion, vety little of its abstract formalism is used. The part used is either discussed in the text or the results for the group under discussion are stated pointing out the analogy between these results and those of the familiar rotation group. (auth)
