N2 - A possible equivalence of scalar dark matter, the inflaton, and modified gravity is analyzed. After a conformai mapping, the dependence of the effective Lagrangian on the curvature is not only singular but also bifurcates into several almost Ein-steinian spaces, distinguished only by a different effective gravitational strength and cosmological constant. A swallow tail catastrophe in the bifurcation set indicates the possibility for the coexistence of different Einsteinian domains in our Universe. This 'triple unification' may shed new light on the nature and large scale distribution not only of dark matter but also on 'dark energy', regarded as an effective cosmological constant, and inflation.
