| Abstract: | We introduce a new method for generating initial conditions consistent with
highly nonlinear observations of density and velocity fields. Using a variant of
the Least Action method, called Perturbative Least Action (PLA), we show
that it is possible to generate several different sets of initial conditions, each
of which will satisfy a set of highly nonlinear observational constraints at the
present day. We then discuss a code written to test and apply this method and
present the results of several simulations. |
