Query: Kaluza-Klein reduction of conformally flat spaces   Kaluza-Klein reduction of conformally flat spaces is considered for arbitrary
dimensions. The corresponding equations are particularly elegant for the
reduction from four to three dimensions. Assuming circular symmetry leads to
explicit solutions which also arise from specific two-dimensional dilaton
gravity actions.
