"The Lagrangian resummation theory"

The large-scale structure (LSS) of the universe has attracted renewed
interests these days, as a probe of such as the dark energy,
primordial non-Gaussianity, and modified gravity, etc. Many ambitious
plans of galaxy redshift survey have been proposed, including BigBOSS,
HETDEX, LAMOST, SKA, SuMIRe, Eulid, WFIRST, etc. Understanding precise
properties of dynamics in LSS is crucial to extract cosmological
information from those huge redshift surveys. We have developed a new
approach to the nonlinear perturbation theory, which is called the
Lagrangian resummation theory (LRT), to predict the observable power
spectrum and polyspectra. The biasing and redshift-space distortions
are naturally incorporated in this approach. Once a model of galaxy
biasing is given, no free parameter is present in this theory.
