= Quasi-primary operator
{title2=$(h,\widetilde h)$}
A <quasi-primary operator> transforms with weights $(h,\widetilde h)$ under global conformal, or Möbius, transformations. A <primary operator> has this covariance under every locally invertible holomorphic and antiholomorphic coordinate change. In <radial quantization>, quasi-primary states are annihilated by $L_1,\widetilde L_1$, whereas <primary states> are annihilated by every positive Virasoro mode. The stress tensor at nonzero <central charge> is quasi-primary but not primary because its transformation under a general coordinate change includes a Schwarzian term.
