We give an overview of literature related to Jurgen Ehlers’ pioneering 1981 paper on Frame theory—a theoretical framework for the unification of general relativity and the equations of classical Newtonian gravitation. This unification encompasses the convergence of one-parametric families of four-dimensional solutions of Einstein’s equations of General relativity to a solution of equations of a Newtonian theory if the inverse of a causality constant goes to zero. As such the corresponding light… 

1+3 -Newton-Cartan system and Newton-Cartan cosmology

We perform a covariant 1+3 split of the Newton-Cartan equations. The resulting 3-dimensional system of equations, called the 1+3-Newton-Cartan equations, is structurally equivalent to the 1+3Einstein

On general-relativistic Lagrangian perturbation theory and its non-perturbative generalization

: The Newtonian Lagrangian perturbation theory is a widely used framework to study structure formation in cosmology in the weakly nonlinear regime. We review a general-relativistic formulation of

On average properties of inhomogeneous fluids in general relativity III: general fluid cosmologies

We investigate effective equations governing the volume expansion of spatially averaged portions of inhomogeneous cosmologies in spacetimes filled with an arbitrary fluid. This work is a follow-up to

Existence of families of spacetimes with a Newtonian limit

Jürgen Ehlers developed frame theory to better understand the relationship between general relativity and Newtonian gravity. Frame theory contains a parameter λ, which can be thought of as 1/c2,

Dynamics of Gravitational Instability Is Nonlocal

Few recent generations of cosmologists have solved non-local newtonian equations of the gravitational instability in an expanding universe. In this approach pancaking is the predominant form of first

Lagrangian theory of structure formation in relativistic cosmology: Lagrangian framework and definition of a nonperturbative approximation

In this paper, we present a Lagrangian framework for the description of structure formation in general relativity, restricting attention to irrotational dust matter. As an application we present a

On the existence of rotating stars in general relativity

AbstractThe Newtonian equations of motion, and Newton's law of gravitation can be obtained by a limit $$\lambda = \frac{1}{{c^2 }} \to 0$$ of Einstein's equations. For a sufficiently small constant

Newtonian Cosmology in Lagrangian Formulation: Foundations and Perturbation Theory

The “Newtonian” theory of spatially unbounded, self-gravitating, pressureless continua in Lagrangian form is reconsidered. Following a review of the pertinent kinematics, we present alternative

Newtonian gravity on the null cone

For a general relativistic ideal fluid, we analyze the Newtonian limit of the initial value problem set on a family of null cones. The underlying Newtonian structure is described using Cartan’s

Lagrangian Perturbation Approach to the Formation of Large-scale Structure

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

Do Black Holes Exist in a Finite Universe Having the Topology of a Flat 3-Torus?

Based on perturbation theory, we present the exact first-order solution to the Einstein equations for the exterior static gravitational field of an isolated non-rotating star in a spatially finite

Lagrangian theory of structure formation in relativistic cosmology. IV. Lagrangian approach to gravitational waves

The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the perturbation and solution schemes that are generated by the spatially projected

The Newtonian limit for asymptotically flat solutions of the Vlasov-Einstein system

It is shown that there exist families of asymptotically flat solutions of the Einstein equations coupled to the Vlasov equation describing a collisionless gas which have a Newtonian limit. These are
