Uniqueness of asymptotically conical K\"ahler-Ricci flow

报告人：陈龙腾（巴黎萨克雷大学）时 间：2025年8月19日（星期二），上午10:00-11:00地 点：海纳苑2幢102摘 要：A K\ahler cone appears as a normal algebraic variety with one isolated singular point, and the K\ahler-Ricci flow is expected to desingularize this singularity instantaneously. A precise example is given by Feldman, Ilmanen and Knopf in 2003. For any integers $k>n\ge 2$ and re...

Rectifiability of the Stratification for Harmonic Map Flows via Tangent Measures

报告人：王尉 博士（北京大学）时 间：2025年6月5日（星期四），上午10:30-11:30地 点：海纳苑2幢203摘 要：We investigate the stratification theory for ``suitable solutions of harmonic map flows based on the spatial symmetry of tangent measures. Generally, suitable solutions are a category of solutions that satisfy both the localized energy inequality and the monotonicity formula. Bu...

The energy identity of Ginzburg-Landau approximation of harmonic maps

报告人：李轩宇 博士（康奈尔大学）时 间：2025年6月5日（星期四），上午9:30-10:30地 点：海纳苑2幢203摘 要：The harmonic map is the critical point of energy functional of maps into a manifold. Unlike harmonic functions, the convergence of harmonic maps may not be strong in W^{1,2} space. It turns out that the loss of energy in the convergence of harmonic maps can be computed by the...

Quantitative maximal diameter rigidity of positive Ricci curvature

报告人：任天寅 博士后（厦门大学）时 间：2025年5月19日（星期一），上午9:30-10:30地 点：海纳苑2幢202摘 要：In Riemannian geometry, the Cheng’s maximal diameter rigidity theorem says that if a complete $n$-manifold $M$ of Ricci curvature, $\Ric_M \ge (n − 1)$, has the maximal diameter $\pi$, then $M$ is isometric to the unit sphere. The main result in this paper is a quantitative...
