A Renormalisation Approach to Effective Interactions in Hilbert Space
J. Richert
abstract: The low-lying bound states of a microscopic quantum many-body system of $n$
particles and the related physical observables can be worked out in a truncated
$n$--particle Hilbert space. We present here a non-perturbative analysis of
this problem which relies on a renormalisation concept and work out the link
with perturbative approaches.
