Abstract: |
The development of large scale structure of the universe into the nonlinear regime can be studied using erturbation theory techniques. Recently a new scheme has emerged, the Renormalized Perturbation Theory, that orrows techniques from quantum field theory and that provides renewed insights into the physics of osmological gravitational clustering. In this talk I will present this new approach and recent results that have been obtained with either a Eulerian escription or a Lagrangian description of the fluid otion equations. |
