研究領域

幾何分析Geometric Analysis

以網格線繪製的懸鏈曲面,形狀像上下兩端開口、中間收窄的沙漏形管子,中央有一條鉛直的虛線對稱軸;朝向觀看者的網格線顏色較深,背面的較淺。
懸鏈曲面(catenoid)(cosh v cos u, cosh v sin u, v):平均曲率處處為零的極小曲面。Euler 於 1744 年發現;除平面外,它是唯一的旋轉極小曲面(不計相似變換)。

幾何分析(geometric analysis)以分析學的方法,特別是非線性偏微分方程與變分法,研究流形的幾何與拓樸性質。許多幾何問題可化為偏微分方程問題:例如極小曲面是面積泛函的臨界點,其平均曲率處處為零;具有指定曲率的黎曼度量是否存在,則歸結為相應橢圓型方程的可解性。

代表性主題包括極小曲面與調和映射、Yamabe 問題、Ricci 流與平均曲率流等幾何演化方程,以及曲率條件對流形拓樸的限制。Hamilton 提出的 Ricci 流方法經 Perelman 完成,證明了 Poincaré 猜想與 Thurston 幾何化猜想,是此領域的重要里程碑。
