Annamalai Ramanathan
Annamalai Ramanathan (born August 29, 1946 in Madras , † March 12, 1993 in Chicago ) was an Indian mathematician who dealt with algebraic geometry and representation theory .
Ramanathan studied mathematics at Ramakrishna Mission Vivekananda College in Chennai with a bachelor's degree. He received his doctorate in 1977 with S. Ramanan at the Tata Institute of Fundamental Research and was professor there. He was also visiting professor and researcher in Bonn, at the University of Illinois at Urbana-Champaign , at the Institute for Advanced Study (1978/79) and at Johns Hopkins University . He died of a heart attack while visiting Chicago.
With S. Ramanan he dealt with Schubert varieties and flag varieties. With Vikram Bhagvandas Mehta (* 1946) he introduced the concept of Frobenius splitting of algebraic varieties, which led to the solution of several problems from the geometry of the Schubert varieties, including the proof of the Demazure character formula in the representation theory of Lie algebras ( compiled by Michel Demazure 1974, but his proof turned out to be incomplete) by HH Anderson 1985.
He received the Shanti Swarup Bhatnagar Prize in Science and Technology with Mehta in 1991 .
