Interactions and Kernels

  • Heinrich Saller
Part of the Fundamental Theories of Physics book series (FTPH, volume 163)


It is physically obvious that interactions and bound-states have a close connection. Both are described, in distinction to free objects, by nonabelian operations of nonflat position. In contrast to position functions, which are representation coefficients of position groups, position interactions are formalized by linear mappings of position functions and are, in general, position distributions. The relation between bound-states and interactions will be seen in parallel to the relation between Lie groups and Lie algebras.
