Conformal transformation/ Weyl scaling are they two different things? Confused! Thanks I am clear about this point and I understand "undoing" by multiplying by the inverse of the function still gives a different space time. Where as conformal transformation does not change space-time just different coordinate label. I would try and attach a link to that paper then you might be able to tell where I am going wrong but not on this point. Thanks |

Conformal transformation/ Weyl scaling are they two different things? Confused! Thanks a lot! it is clear when they are different. My confusion has to do with a paper I read. " Rev. Mod. Phys. 34, 442–457 (1962) Conformal Invariance in Physics" by L.Witten et al.. They talk about active point transformation and define a corresponding coordinate transformation to define a conformal transformation, which amounts to I think, rescaling the metric thus weyl transformation in our lingo. they call this $C_{g}$ however they say that special conformal transformation is a subgroup of these transformations with the usual lie-algebra in our lingo "conformal is a subgroup of weyl" ?? |
