陈省身的合作者，著名的 Renaissance Technologies/Medallion Fund 的 owner， Jim Simons 过世了，一个传奇式的人物。
Simons'' mathematical work primarily focused on the geometry and topology of manifolds. His 1962 Berkeley PhD thesis, written under the direction of Bertram Kostant, gave a new proof of Berger''s classification of the holonomy groups of Riemannian manifolds. He subsequently began to work with Shing-Shen Chern on the theory of characteristic classes, eventually discovering the Chern–Simons secondary characteristic classes of 3-manifolds. Later, mathematical physicist Albert Schwarz discovered early topological quantum field theory, which is an application of the Chern–Simons form. It is also related to the Yang-Mills functional on 4-manifolds, and has had an effect on modern physics. These and other contributions to geometry and topology led to Simons becoming the 1976 recipient of the American Mathematical Society (AMS) Oswald Veblen Prize in Geometry.[20] In 2014, he was elected to the U.S. National Academy of Sciences.[21]
Simons'' Renaissance Technologies'' hedge funds, which trade in markets around the world, have employed mathematical models to analyze and execute trades, many automated. Renaissance uses computer-based models to predict price changes in financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions. Medallion, the main fund which is closed to outside investors, has earned over $100 billion in trading profits since its inception in 1988. This translates to a 66.1% average gross annual return or a 39.1% average net annual return between 1988 – 2018.

Jim Simons, a mathematician who founded the most successful quantitative hedge fund of all time, passed away on Friday in New York City, his foundation announced on its website.
