From SR to GR in an "easy" math (and physical) way
Hello..i know that for example to go from Newtonian to SR you take:
\frac{du}{ds}=0 \rightarrow \nabla _{u} u=0
My question is ¿is there an "easy" form to go from SR to GR in the form:
\nabla _{u} u=0 \rightarrow \nabla R_{ab} =0
Or to get Einstein equation appart from using the Lagrangian formalism... using "Differential Geomertry" or similar...
