Annamalai Ramanathan

Annamalai Ramanathan ( born August 29, 1946 in Madras, † 12 March 1993 in Chicago) was an Indian mathematician who dealt with algebraic geometry and representation theory.

Ramanathan studied at Ramakrishna Mission Vivekananda College in Chennai mathematics with a bachelor 's degree. He received his doctorate in 1977 at S. Ramanan at Tata Institute of Fundamental Research, where he was professor. He was also a visiting professor and visiting scientists in Bonn, at the University of Illinois at Urbana- Champaign, at the Institute for Advanced Study (1978 /79) and Johns Hopkins University. He died of a heart attack during a visit to Chicago.

With S. Ramanan he dealt with Schubert varieties and flag varieties. With Vikram Bhagvandas Mehta ( born 1946 ), he introduced the notion of Frobenius decomposition ( Frobenius splitting) of algebraic varieties one that led to the solution of several problems from the geometry of Schubert varieties, including the proof of the Demazure character formula in the representation theory of Lie algebras ( prepared by Michel Demazure 1974, but his proof turned out to be patchy out ) by HH Anderson 1985.

He received the Shanti Swarup Mehta 1991 Bhatnagar Prize in Science and Technology.
