[<< wikibooks] General Relativity/Notes to GR editors

Since I am sure I'm not the only one who will be editing this page, let's agree on some standards so that everything is cohesive. Here are my suggestions:
1. Certainly we should use follow the Einstein summation convention.
2. Let's agree to use the same signature for the Minkowski metric. I propose the
(
−
+
+
+
)
{\displaystyle (-+++)}
signature, i.e., the Minkowski metric
η
{\displaystyle \mathbf {\eta } }
is given by
η
(
u
,
v
)
=

{\displaystyle \mathbf {\eta } (\mathbf {u} ,\mathbf {v} )=-u^{0}v^{0}+u^{1}v^{1}+u^{2}v^{2}+u^{3}v^{3}}
.
