Using perturbative least action to reconstruct redshift-space distortions

In this paper, we present a redshift-space reconstruction scheme that is an alogous to and extends the perturbative least action (PLA) method described by Goldberg & Spergel. We first show that this scheme is effective in reco nstructing even nonlinear observations. We then suggest that by varying the cosmology to minimize the quadrupole moment of a reconstructed density fie ld, it may be possible to lower the error bars on the redshift distortion p arameter, beta, as well as to break the degeneracy between the linear bias parameter, b, and Omega (M). Finally, we discuss how PLA might be applied t o realistic redshift surveys.
