Question

What does this mean?

Answer 1

Idk sry

Answer 2

\[\huge{\nabla_{\partial_i}}\partial_j=\sum_k\Gamma_{ij}^*\partial_k\]

Answer 3

Thanks UnkleRhaukus. Could you please explain what formula this is? Cheers

Answer 4

I think that right side is like below:
\[\huge \sum\limits_k {\Gamma _{ij}^k\frac{\partial }{{\partial {x^k}}}} \]
where \(\Large {\Gamma _{ij}^k}\) can be an affine connection, or Christoffel symbol
