Canonical formulation of scalar curvature squared action in higher dimensions

The canonical formulation for an action containing a scalar curvature squared term (R-2) in arbitrary dimension has been performed in a Robertson-Walker minisuperspace model. The quantum dynamics does not alter significantly from the same in four dimensions, while the continuity equation picks up a particular operator-ordering index. The classical solution is also at par with the one presented by Starobinsky for k = 0 and matches with the extremum of the effective potential. Semiclassical approximation peaks around the classical solution.
