X.Calculating the Lie Derivative of a One-Form with Respect to a Vector Field

Click For Summary
The discussion focuses on calculating the Lie derivative of the one-form ω = 3 dx_1 + 4x dx_2 with respect to the vector field X = 7x ∂/∂x_1 + 2 ∂/∂x_2. Participants express a need for clarification on the variable "x" in the term 4x dx_2, indicating that it requires proper indexing for accurate computation. The formula for the Lie derivative is acknowledged, but there is hesitation due to a lack of confidence in applying it correctly. The conversation highlights a perceived gap in responses, questioning whether the problem is too simple or if it requires more detailed explanation. Ultimately, clarity on the indexing of variables is essential for proceeding with the calculation.

I'd like an example of calculating the Lie derivative of a one-form with respect to a vector field, for example, the one-form

<br /> \omega = 3 dx_1 + 4x dx_2<br />

with the vector field

<br /> X = 7x \frac{\partial }{\partial x_1} + 2 \frac{\partial }{\partial x_2} <br />

Any input would be appreciated.

i am also one waiting for a reply to this post
i have the formula to compute lie derivatives of one forms but not enough self-confidence to give an exact soln .actually i also did not understand which x do you talk about when saying 4xdx_2
i think here in this forum people have enough knowledge to answer but i could not understand why there is no reply .Is it too simple to answer?

^No, it doesn't make any sense until an index is put on the "x" in the vector and the 1-form. After that, as you say, just use your formula for Lw
