Worldsheet conformal Killing group (source code)

= Worldsheet conformal Killing group

The worldsheet conformal Killing group is the connected residual group of conformal automorphisms of the chosen compact <Riemann surface>. Its infinitesimal vectors satisfy the <Conformal Killing equation>, or $P_1v=0$ for the <worldsheet diffeomorphism ghost operator>. Its complex dimensions are three on a sphere, one on a torus, and zero for <genus> at least two. The sphere group consists of <Möbius transformations>, while the torus's connected group is translation. Additional discrete automorphisms are handled by the moduli quotient rather than counted as continuous zero modes.
