The dispersion relations for an arbitrary di rection scattering amplitude are proven, and analytic properties of the amplitude in the plane of the complex cosine of the scattering angle are studied in detail.

This book contains a systematic analysis of the formalisms of quantum electro dynamics in the presence of an intense external field able to create pairs from the vacuum, and thereby violate the stability of the latter.

The December 1988 issue of the International Journal of Modern Physics A is dedicated to the memory of Tony Hilton Royle Skyrme. It contains an informative account of his life by Dalitz and Aitchison's reconstruction of a talk by Skyrme on the origin of the Skyrme model.

Contents:- Introduction- Preliminaries and Simple Models- Currents, Anomaly, Solitons, and Fractional Fermions- More on Chiral Symmetry- Introduction to Instantons- Relevance of Instantons- Chiral Perturbation Theory- The Topological and Non-Topological Soliton Model- QCD Sum Rules- References

In many respects the motions of the nucleons can be very well described by an overall mean field, so that the motion of each nucleon is governed by the mean field due to all the other nucleons.

The aim of this book is to provide a single reference source for the wealth of geometrical formulae and relationships that have proven useful in the descrip tion of atomic nuclei and nuclear processes.

In these days of specialization it is important to bring together physicists working in diverse areas to exchange and share their ideas and excitement. The actual idea to explore the possibility of holding a conference, however, crystallized in the summer of 1989 during a visit of FBM to Abo Akademi.

Out of the large number of existing nuclear systems, few-particle, that is few-nucleon, systems can be singled out to form a special group. In these Lectures we utilize this to study few-body systems in great detail, in particular three-and four-body systems.
