Title: Using Perturbative Least Action to reconstruct redshift space

Abstract: In this paper, we present a redshift space reconstruction scheme which is analogous to and extends the Perturbative Least Action (PLA) method described by Goldberg & Spergel (2000). We first show that this scheme is effective in reconstructing even nonlinear observations. We then suggest that by varying the cosmology to minimize the quadrupole moment of a reconstructed density field, it may be possible to lower the errorbars on the redshift distortion parameter, β as well as to break the degeneracy between the linear bias parameter, b, and UM. Finally, we discuss how PLA might be applied to realistic redshift surveys.
