Can someone help understand this scaling argument and the proof(?) that there is a conformal symmetry in Navier-Stoke's equation? (..am I even reading the result right?..)
Is one saying that the equations 3.4 encode the full symmetry of equation 1.1? If yes, how? What calculation do I need to do to check that?
I am unable to understand how to read 3.4
Also what role does equation 2.9 play? Are the new symmetries specific to the form 2.9 or they apply to the general 1.1?
Also 2.9 and 1.1 don't seem to be the "same" as apparently claimed- 2.9 has the time derivative of a0 and also a viscosity-Ricci term. What's going on?
