The proposal has two main components. The first attempts to describe nucleon structure, and the interactions between nucleons in terms of Quantum Chromo dynamics, (QCD). There are two regions with a straight forward connection: short distances, where asymptotic freedom allows a perturbative treatment in terms of quarks and gluons, and large distances, where nucleons appear as manifestations of the non-linear nature of QCD at large distances: the latter leads to a picture of nucleons as solutionis, and can be handled in the large N (number of colors) and classical limit, while interactions between them can be described in terms of multi meson exchange. ("QCD at small q is a complicated non-linear theory of mesons "Witten). The aim is to understand the connection between these two pictures. As a start 1/N and quantum corrections to the solutionis picture are to be tackled. The second component is to continue the study of scattering theory with techniques that combine algebraic and analytic techniques: this has applications to molecular as well as nuclear physics.
