I'm looking for a reference that lists generators of two dimensional conformal group on a complex sphere in terms of differential operators that may act on quasi primary fields ϕ(z,ˉz). E.g. dilatation operator acts as D=z∂∂z:
z∂∂zϕ(z,ˉz)=Δϕ(z,ˉz) , ˉz∂∂ˉzϕ(z,ˉz)=ˉΔϕ(z,ˉz)
with left moving and right moving dimensions Δ,ˉΔ.
How do the rest of the generators P,J,K act?
This should be pretty standard stuff, but I've been googling a while now and it seems to be very elusive.
