Additional Topics in GeometryWe have already encountered diffeomorphisms in the previous chapter as one-to-one invertible bothways-differentiable maps of a manifold onto itself. We now define maps between different manifolds.

Arthropathy

The Einstein EquationWe have learnt something about the left-hand side of the Einstein equation . in chapters on geometry. It is time now to have a look at the equation itself.

Schwarzschild and Kerr SolutionsFor the purpose of simplifying formulas, we use a unit of time so that t stands for ct and unit of mass so that 2M stands for 2GM/c. in this chapter except for section 14.4 where c and G appear as usual.
