Mr. Chan Shan Tai (M.Phil. Student)
In the article "On the global rigidity of the p-th root embedding" Mr. CHAN Shan Tai solved the characterization problem of the p-th root map up to congruence among holomorphic isometries between the disk and the p-disk, resolving a problem that was left open since the Ph.D. thesis of Dr. NG Sui Chung in 2008.The article, written while Mr. Chan was an M.Phil. student, has been accepted for publication in the Proceedings of the AMS. According to the referee, "the results obtained in this article have made considerable contribution to the classification problem of
holomorphic isometric embeddings among bounded symmetric domains", while "the analysis employed in the article is elegant and the presentation of ideas is also very transparent".
Dr. Zhang Yunxin (Ph.D. Graduate)
The thesis is a first systematic treatise on the topic of geometric substructures modeled on varieties of minimal rational tangents (VMRTs) concerning uniruled projective manifolds, where geometric substructures play a role in VMRT Geometry analogous to that of Riemannian submanifolds in Riemannian geometry. According to the External Examiner, "the thesis is an important contribution to the problem of characterization of standard embeddings of rational homogeneous spaces, which opens new perspective for future researches. Yunxin Zhang shows
great skill in various areas, e.g., he combines representation theory with classical projective geometry. He builds upon very recent research and contributes himself in it."
