Let $X$ be a Kähler manifold, with Kähler form $\omega$, then Kähler ricci flow introduced by S.T.Yau as

$$\frac{\partial \omega}{\partial t}=-Ric(\omega)+\lambda\omega$$ If the initial metric $\omega_0$ be Kähler, then all metrics along Kähler Ricci flow are Kähler metrics.

In fact Kähler resolves the singularities and could be seen as PDE surgery. This is the main philisophy of Kähler Ricci flow.

For a pair $(X,D)$ where $D$ is a divisor with conic singularities, then we can replace Kähler-Ricci flow with the following equation as conical Kähler Ricci flow

$$\frac{\partial \omega}{\partial t}=-Ric(\omega)+\lambda\omega+[D]$$

where $[D]$ is the current of integration
