Homework Statement



Let va be a dual vector field. Show that the quantity ∂[a vb] transforms as a type (0, 2) tensor under coordinate transformations.


Homework Equations



wu' = (dxu / dxu') wu

The Attempt at a Solution



My main problem is that I don't know what the brackets mean.

I know if they weren't there it doesn't transform like a tensor because there's a second derivative when you do out the math and it's non-tensorial that way.

Does anyone know of a good online resource that describes how to transform vectors? My textbook doesn't give very concrete examples.

You seem to be saying that you are trying to do a problem involving "[itex]\partial_{[a }v_{b][/itex]" without knowing what it means. If so, then the first thing you should do it look it up! Where did you get this problem? If it is from a textbook, it will certainly be defined in the book. If you were give this problem by an instructor, ask the instructor. That is generally better than asking other people because they may have learned definitions that differ from the one you need to use.
 

1. What is a dual vector transformation?

A dual vector transformation is a mathematical operation that converts a vector in one vector space into a dual vector in a different dual vector space.

2. How is a dual vector transformation represented?

A dual vector transformation is typically represented as a matrix, where the columns of the matrix are the coordinates of the dual vectors in the original vector space.

3. What is the purpose of a dual vector transformation?

The purpose of a dual vector transformation is to allow for calculations involving both vectors and dual vectors in different vector spaces. It is also useful in solving problems in physics and engineering.

4. What is the relationship between a vector transformation and a dual vector transformation?

A vector transformation and a dual vector transformation are closely related, as they both involve operations on vectors. However, a vector transformation operates on vectors in the same vector space, while a dual vector transformation operates on vectors in different dual vector spaces.

5. How is a dual vector transformation calculated?

A dual vector transformation is calculated by multiplying the vector by the transformation matrix. The result is a dual vector in the dual vector space. The process of calculating a dual vector transformation is similar to calculating a regular vector transformation.
