We study the complete Kähler-Einstein metric of a Hartogs domain Ω̃ built on an irreducible bounded symmetric domain Ω, using a power N of the generic norm of Ω. The generating function of the Kähler-Einstein metric satisfies a complex Monge-Ampère equation with boundary condition. The domain Ω̃ is in general not homogeneous, but it has a subgroup of automorphisms, the orbits of which are paramet...

We develop several formal analogies between the logistic equation and spatially homogeneous isotropic relativistic cosmology described by Einstein–Friedmann equations. These produce an effective Lagrangian Hamiltonian new symmetries for equation.
