TITLE: A family of Kahler flying wing steady Ricci solitons

ABSTRACT: Steady Kahler-Ricci solitons are eternal solutions of the Kahler-Ricci flow. I will present new examples of such solitons with strictly positive sectional curvature that live on C^n and provide an answer to an open question of H.-D. Cao in complex dimension n>2. This is joint work with Pak-Yeung Chan and Yi Lai.

TITLE: Classification results for expanding and shrinking gradient Kähler-Ricci solitons

ABSTRACT: A complete Kahler metric g on a Kahler manifold M is a “gradient Kahler-Ricci soliton” if there exists a smooth real-valued function f:M\to\mathbb{R} with \nabla f holomorphic such that \operatorname{Ric}(g)-\operatorname{Hess}(f)+\lambda g=0 for \lambda a real number. I will present some classification results for such manifolds. This is joint work with Alix Deruelle (Université Paris-Sud) and Song Sun (UC Berkeley).
