Life

Lê Dũng Tráng went to France in the 1950s, where he attended the Lycée Louis-le-Grand . He received his doctorate in 1969 and 1971 (two-part French doctorate) with Claude Chevalley (and Pierre Deligne ) at the Sorbonne . For twenty years from 1975 to 1999 he was Professor at the University of Paris VII and Research Director of the CNRS . 1983 to 1995 he was also a professor at the École polytechnique . From 2002 to 2009 he headed the mathematics department at the International Center for Theoretical Physics (ICTP) in Trieste .

He has been a frequent visiting scholar at Harvard University (with Phillip Griffiths ) and Northeastern University ( Terence Gaffney , David B. Massey ).

He is particularly concerned with singularity theory in the complex (Milnor fibers, use of polar varieties, perverse sheaves).

In 2000 he was involved in establishing scientific exchange between the USA and Vietnam. For this he received an honorary doctorate from the Vietnamese Academy of Sciences in 2004. He is a Fellow of the Third World Academy of Sciences .

His PhD students include Hélène Esnault and Claude Sabbah .
