Several papers on topics pertaining to geometric analysis are presented: Christian Baer and Werner Ballmann on boundary value problems for elliptic differential operators of the first order; Simon Brendle on rigidity phenomena involving scalar curvature; Simon Donaldson on stability, birational transformations, and the Kähler-Einstein problem; D. H. Phong, Jian Song, and Jacob Sturm on complex Monge-Ampere equations; Weimin Sheng, Neil S. Trudinger, and Xu-Jia Wang on the k-Yamabe problem; and S.-T. Yau on further topics of geometric analysis. Also presented are papers by Gergely Berczi and Frances Kirwan on a geometric construction for invariant jet differentials; B. Bramham and H. Hofer concerning symplectic dynamics; Dominic Joyce on C infinity schemes and C infinity algebraic geometry; Kenji Fukaya, Yong-Geun Oh, Hiroshi Ohta, Kaoru Ono on Lagrangian Floer theory of compact toric manifolds; and Paul Seidel on Fukaya categories.
Chuan-Chih Hsiung began teaching at Lehigh University in 1952. In 1967, he founded the Journal of Differential Geometry, an influential journal in its field, and served as its editor-in-chief till his death in 2009.
