A comparison of oscillation frequencies of rotating stars obtained by   one- and two-dimensional calculations
  We discuss how the p- and g-mode frequencies calculated for rotating stars are affected by the way of including the centrifugal deformations. We find that p-mode frequencies are sensitive to the accuracy in treating the centrifugal deformation, while the effect becomes smaller for smaller frequencies in the g-mode range.
