Query: Toric Kahler Metrics: Cohomogeneity One Examples of Constant Scalar
  Curvature in Action-Angle Coordinates   In these notes, after an introduction to toric Kahler geometry, we present
Calabi's family of U(n)-invariant extremal Kahler metrics in symplectic
action-angle coordinates and show that it actually contains, as particular
cases, many interesting cohomogeneity one examples of constant scalar
curvature.
