Lê Dũng Tráng, (born 1947 in Saigon) is a Vietnamese- French mathematician.
Life and work
At the end 1949, Lê Dũng Tráng came to France, where he attended the Lycée Louis-le-Grand in Paris. He obtained a Ph.D. degree at the University of Paris in 1969 and 1971 under the supervision of Claude Chevalley and Pierre Deligne. [1] From 1975 to 1999, he was professor at the University of Paris VII and research director of the CNRS. From 1983 to 1995 he was also a professor at the École Polytechnique. From 2002 to 2009 he headed the department of mathematics at the International Centre for Theoretical Physics (ICTP), in Trieste, Italy.
He was a frequent guest scientist at Harvard University (with Heisuke Hironaka) and Northeastern University (with Terence Gaffney and David B. Massey).
He is particularly concerned with singularity theory in the complex domain ( Milnor fibrations, perverse sheaves).
In 2000 he was involved in promoting scientific exchange between the United States and Vietnam. [2] For this, he received an honorary doctorate from the Vietnam Academy of Science and Technology in 2004. [3] He is a Fellow of the Third World Academy of Sciences since 1993.
His students include Hélène Esnault and Claude Sabbah.
