Abstract: I will review various perturbation theory (PT) approaches to large scale structure (LSS) of the universe, including Eulerian and Lagrangian PT, discuss their shortcomings, and present some solutions to them. Some applications of PT in LSS that I will discuss include power spectrum, with and without wiggles and primordial features, bi and tri-spectrum (covariance matrix), biasing and redshift space distortions.
