I have some basic questions. The settings are following.



Let $M$ be a complex manifold (Actually, it is a kahler maniold.), $alpha=$Im$barpartial phi$, and $omega=-dalpha$. Define a vector field $V$ by $i(V)omega=-alpha$. (here, $i$ : interior product).



Let $phi$ be a real analytic function satisfying $V phi=2phi$. (*)



My question is



  1. how the equation (*) can be written in local holomorphic coordinates as $$phi_a phi^a=2phi$$
    or $$ phi^abarbphi_a phi_barb=2phi$$

where $phi_a = fracpartial phipartial z^a$ and $phi^a$ is defined by $phi_barb=sqrt-1phi_abarbphi^a$ .



and 2. Why this equation is called "Monge-Ampere type" equation. I know just the definition about 'Monge-Ampere equation' : some PDE with the term of determinant of hessian matrix.



Thanks.
(If there is some recommended book, please let me know.)
