‣ Re-summation can be extended to any order FB, Crocce, Scoccimarro, PRD, 2008 In the large k limit we have : ‣ Non-Gaussian initial conditions ‣ The Gamma-expansion is still valid. ‣ In the large k limit we now have : G(k) → exp [ − Crocce, Sefusatti, FB, 2010 ∞∑ p=2 〈(v.k) p 〉 c p! (e η − e η 0 ) p ] instead of G(k) → exp [ ] − 〈(v.k)2 〉 c (e η − e η 0 ) 2 2 for Gaussian initial conditions. 28
