,On Compact Einstein Kähler Manifolds with Abundant Holomorphic Transformations, = kg for some k ∈ R. If we denote by γ the Ricci form of (M,J,g) (γ(X,Y) = Ric(g)(X,JY)) and by ω the Kähler form, (M,J,g) is Einstein if and only if γ = kω (k ∈ R). Let H. (M, ℝ) denote the 2nd cohomology group with the coefficients in R. It is known that the first Chern class c. (M) of a compact Kähler manifold (M, J, g) is given by ..
