Scalar V-soliton equation and K\"ahler-Ricci flow on symplectic quotients

29 Jan 2020  ·  Li Chang ·

In this paper, we consider the $V$-soliton equation which is a degenerate fully nonlinear equation introduced by La Nave and Tian in their work on K\"ahler-Ricci flow on symplectic quotients. One can apply the interpretation to study finite time singularities of the K\"ahler-Ricci flow... As in the case of K\"ahler-Einstein metrics, we can also reduce the $V$-soliton equation to a scalar equation on K\"ahler potentials, which is of Monge-Amp\`ere type. We formulate some preliminary estimates for such a scalar equation on a compact K\"ahler manifold $M$. read more
