Use of abstract Index notation in FORMAL DEFINITION
I think that It is mixed the use of the abstract index notation and the local chart index notation, and that could be measleading. mantener refrigerado (talk) 07:30, 11 August 2019 (UTC)


 * No, it is not. Writing $$\nabla_{\dot\gamma}{\dot\gamma} $$, where $$\nabla $$ denotes the covariant derivative associated to $$\Gamma$$, is not using abstract index notation. Aurel.droud (talk) 08:49, 27 December 2019 (UTC)
