Résumé de l'exposé

Let $(M,g,X)$ be a complete gradient Kähler–Ricci expander with quadratic curvature decay (including all derivatives). Its geometry at infinity is modeled by a unique asymptotic cone, which takes the form of a Kähler cone $(C0,g0)$. In this talk, we will show that if there exists a solution to the Kähler–Ricci flow on $M$ that desingularizes this cone, then it necessarily coincides with the self-similar solution determined by the soliton metric $g$. Furthermore, if one perturbs the soliton metric in a suitable manner, the resulting initial data generates an immortal solution to the Kähler–Ricci flow which, after appropriate rescaling, converges to an asymptotically conical gradient Kähler–Ricci expander.
