Classical General Relativity  

In General > s.a. einstein's equation; history of gravitational physics.
* Motivation: (i) Inadequacy of concept of (global) inertial frames, and need to formulate a theory that does not have preferred reference frames; (ii) Inconsistency of Newtonian gravity with special relativity and indications that gravity can be associated with (geometrical) properties of spacetime; (iii) Equivalence principle.
* Idea: Gravity is a property of spacetime; Matter curves spacetime, and test bodies follow geodesics in the curved geometry.
* Formalism: The gravitational field is a metric tensor on a manifold with only a topology and differentiable structures as background; The theory comes out also if one looks for a self-interacting massless spin-2 field with stress-energy as source; But this will not work for quantum gravity, and has trouble with things like topology.

Approaches, Dynamical Aspects, and Effects > s.a. 3D general relativity.
* Idea: Study of the dynamics of the theory, including exact solutions and approximation methods, the initial value and canonical formulation, gravitational waves and radiation; And global properties of spacetime, including its topology, causal structure, and singularities.
