Let ϕ be a local flow of a vector field X on a Riemannian manifold ( M, g). We see that L X g = f g if a flow consists of conformal maps because of the formula: ( L X g) x = d d t ( ( ϕ t) ∗ g) x t = 0. Unfortunatelly I have a problem with showing inverse i.e. that L X g = f g implies that flow consists of conformal maps. differential ...
WebOct 15, 2024 · Conformal vector fields which never become Killing vector fields under a global conformal change of the metric are called essential conformal vector fields. In Riemannian case, it is well-known that the standard sphere S n and the Euclidean space R n are the only Riemannian manifolds admitting a complete and essential conformal … WebThe conformal trace anomalies for massless scalar, "neutrino," and photon fields propagating in an arbitrary Riemannian space-time are derived. They are seen to be a consequence of the subtraction, during renormalization, of a finite term, $\\ensuremath{\\sim}\\mathrm{ln}({m}^{2}{L}^{2})$, which violates the scale invariance of …

The number of independent conformal transformations is infinite in two dimensions, and finite in higher dimensions. This makes conformal symmetry much more constraining in two dimensions. All conformal field theories share the ideas and techniques of the conformal bootstrap. But the resulting equations are more powerful in two dimensions, where they are sometimes exactly solvable (for example in the case of minimal models), in contrast to higher dimensions, where n…
