@article{Buchert1995LagrangianPA, title={Lagrangian Perturbation Approach to the Formation of Large-scale Structure}, author={Thomas Buchert}, journal={arXiv: Astrophysics}, year={1995} }

The present lecture notes address three columns on which the Lagrangian perturbation approach to cosmological dynamics is based: 1. the formulation of a Lagrangian theory of self--gravitating flows in which the dynamics is described in terms of a single field variable; 2. the procedure, how to obtain the dynamics of Eulerian fields from the Lagrangian picture, and 3. a precise definition of a Newtonian cosmology framework in which Lagrangian perturbation solutions can be studied. While the…
