Seshadri (2010)

CS Seshadri ( Conjeervaram Srirangachari Seshadri; born February 29, 1932 in Kanchipuram ; † July 17, 2020 in Chennai ) was an Indian mathematician who studied algebraic geometry and algebraic groups.

Life

Seshadri studied at the University of Madras (Loyola College) with a Bachelor's degree in 1953 and in 1958 at the University of Mumbai (then Bombay) and the Tata Institute in K. Chandrasekharan doctorate (Generalized multiplicative meromorphic functions on a complex manifold) . From 1953 to 1984 he was at the Tata Institute of Fundamental Research , where he became Professor in 1965 and Senior Professor in 1975. From 1984 to 1989 he was at the Institute of Mathematical Sciences in Chennai (Madras) (IMSc) and from 1989 to 2010 he was founding director of the Chennai Mathematical Institute (CMI).

At first he dealt with modular spaces of curves. In 1965, with MS Narasimhan , he proved a theorem, named after both, about holomorphic vector bundles on Riemann surfaces . According to this, they are stable if and only if they come from an irreducible unitary projective representation of the fundamental group of the Riemann surface.

In the late 1970s he introduced the Standard Monomial Theory into the representation theory of algebraic groups and the geometry of Schubert varieties.

He was a visiting professor at the University of Paris (1957 to 1960), Harvard University (1974/75), UCLA , Brandeis University, the University of Bonn and the University of Kyoto. In 1975/76 he was at the Institute for Advanced Study .

He was invited speaker at the International Congress of Mathematicians in Nice 1970 (Quotient spaces modulo reductive algebraic groups and applications to moduli of vector bundles on algebraic curves).

In 1971 he became a Fellow of the Indian Academy of Sciences, Fellow of the Royal Society and the National Academy of Sciences . He was an honorary doctor from Banaras Hindu University and the University of Hyderabad . He received the Srinivasa Ramanujan Medal from the Indian Academy of Sciences and the Science Award from the Third World Academy of Sciences. In 2009 he received the Padma Bhushan and he received the Shanti Swarup Bhatnagar Prize for Science and Technology. He was a fellow of the American Mathematical Society .
