Question

in tensor analysis notations are killing me...........
represention of a contravariant vector,v= v^ie_i , and for covariant vector v = v_i e^i. why not ..........

Answer 1

contravariant vector \[v= v^ie_i \]
covariant vector \[v = v_i e^i\]
why not contravariant vector \[v=v_i e_i\]
and covariant vector\[v=v^i e^i \]

Answer 2

is e the eigen vector?

Answer 3

basis of the vectors.

Answer 4

and v_i 's are components of veator in e_i 's direction.

Answer 5

yeah ok basis vectors ,

Answer 6

which are the columns and which are the rows
contra , or co

Answer 7

why are you asking for rows and columns?

Answer 8

isn't that the difference ?

Answer 9

i didn't get you.
