The explicit formula of Kähler-Einstein metric and the equivalence of the Kähler-Einstein metric and the Bergman metric on Cartan-Hartogs domains are discussed. A unified explicit formula of Kähler-Einstein metrics on Cartan-Hartogs domains is given. Using this formula and a nature of continuous functions and the unified explicit formula of Bergman metrics, a unified proof of the equivalence of the Kähler-Einstein metric and the Ber...
