[tex]

\int \alpha \sqrt{g} R

[/tex]

where [itex]\alpha[/itex] is a field.

I want to do some kind of coordinate transformation, so that this term in the action becomes

[tex]

\int \sqrt{g}R + \sqrt{g}(...)

[/tex]

where (...) consists of terms containing \alpha.

So basically, I want to remove [itex]\alpha[/itex] from the coefficient of R and move it to other terms in the lagrangian. Now, I know that this can be done! (I remember this from long ago), but for heaven's sake can't figure out how!

Can any one tell me? Just a reference would be fine.
