Query: Quasinormal modes and greybody factors of a four-dimensional Lifshitz
  black hole with z=0   We study scalar perturbations for a four-dimensional asymptotically Lifshitz
black hole in conformal gravity with dynamical exponent z=0, and spherical
topology for the transverse section, and we find analytically and numerically
the quasinormal modes for scalar fields for some special cases. Then, we study
the stability of these black holes under scalar field perturbations and the
greybody factors.
