Lê Dũng Tráng, (born 1947 in Saigon) is a Vietnamese-French mathematician.

Life and work[edit]

In the 1950s, Lê Dũng Tráng came to France, where he attended the Lycée Louis-le-Grand. He obtained a PhD 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 Ecole 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 the Harvard University (with Phillip Griffiths) and Northeastern University (with Terence Gaffney, 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 U.S. 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.

His students include Hélène Esnault and Claude Sabbah.
