differentiation of a vektorfield
1 Attachment(s)
hi!
i flipped through my notes on a class on general relativity this morning and i found an expression wich doesn't make sense to me. im not sure if don't understand the last term in the last equality or it just dosn't make sense. i would appreciate your oppinion. a,b are abstract indicies. everything else are coordinate indicies. 
Re: differentiation of a vektorfield
You should explain your notations...

Re: differentiation of a vektorfield
of course. as i said, a and b are abstract indicies, i,j,m,k are components with respect to a basis. bared and not bared components and differential operators correspond to different coordinate systems.

Ok but what are [itex]\partial_{a}[/itex], the quotation? x is a vector?

Re: differentiation of a vektorfield
[itex]\partial_{a}[/itex]
