In 1966, Yau entered the and his fellow wartime defendants' convictions by Chinese University of Hong Kong to study mathemat means of a coram nobis petition. Yasui consented, ics but moved three years later to the University of and a legal team headed by Oregon attorney Peggy Californiaat Berkeley to pursue graduate studies under Nagae took up his case. Unlike in the case of Fred Chern. At Berkeley, besides working with Chern in Korematsu, however, Yasui's petition failed to bring differential geometry, Yau also studied differential about a reconsideration of the official malfeasance equations with other professors, believing that cross involved in his prosecution.

He wanted rather to develop his own ideas, so he moved next to Stanford University, which offered him a professorship in 1973. Yau, Shing-Tong (1949-) At Stanford Yau enjoyed a period of intense think ing and research on mathematical problems, especially Shing-Tung Yau is a leading mathematician in the on the relationship between differential geometry and world in the late-twentieth and early twenty-firstc entu differential equations. To Yau, Stanford offered an ries, especially in the area of differential geometry and environment of relative isolation that allowed him to partial differential equations, and, as a prominent Chi develop his own ideas. He was, however, able to find nese American scientist, has played an active role in stimulation from young mathematicians there, such as promoting U.S.-China scientificexchange and science Leon Simon and Richard Schoen, and keep in touch and education in mainland China, Hong Kong, and with his friends at Berkeley. Combining his expertise Taiwan. in both differential equations and differential geom Shing-tung Yau (Qiu Chengtong in pinyin) was etry, Yau in 1976 solved the famousCalabi conjecture, born in 1949 in Shantou, Guangdong, China, but grew a study that involved Chern classes. It was perhaps the up in Hong Kong where his father, Qiu Zhenying, was most influential and most important work of Yau's a college philosophy teacher. In the early J 960s, Yau mathematical career and gave rise to the so-called attended the renowned Pei Ching (Peizheng) Middle "Calabi-Yau spaces" that lie at the foundation of string School in Hong Kong and became intensely interested theory, the "theory of everything" that physicists are in plane geometry. His passion for mathematics was trying to devise.
