Neelacanta Sthanumoorthy ( born July 15, 1947  28 January 2020 ) was an Indian Mathematician who worked primarily in the Advanced Mathematics domain of Lie Groups & Lie Algebras, Finite and infinitedimensional KacMoody Lie algebras. He was a Former Professor at Ramanujan Insititute for Advanced Study in Mathematics and Emeritus at UGC. University of Madras.^{[1]} .He obtained a Ph.D. degree in Mathematics from the University of Madras in the year 1982 ^{[2]}and had 36 research publications on topics closely related to Lie (Super) Algebras.
Early life and education
Sthanumoorthy was born in a Tamil family on 15 July 1947 in Nagercoil, India, as the fourth son of six, to Neelacanta Pillai and Anantham Ammal. He finished his schooling in Nagercoil and joined Loyola College as Lecturer in Mathematics in 1978. He then wanted to pursue a career in Advanced Mathematics and joined as a Professor of Mathematics in Ramanujan Institute of Advanced Study in Mathematics (University of Madras) in 1984.
Research
Prof Sthanumoorthy worked on a research problem suggested by Prof.T.S.Bhanumurthy on "Spectra of de Rham Hodge operator on SO(n + 2)/SO(2) × SO(n)" in the year 1982 and was published in Bulletin Sciences and Math. (France). Some of his other research collaborations include Spectral invariant of the zeta function of the Laplacian on $\operatorname{Sp}(r+1)/\operatorname{Sp}(1)\times \operatorname{Sp}(r)$ ^{[3]} , Structure and Root Multiplicities for Two Classes of Extended Hyperbolic KacMoody Algebras Eha 1 (1) and Eha 2 (2) for all Cases, Complete Classification of BKM Lie Superalgebras Possessing Strictly Imaginary Property, Root super multiplicities and corresponding combinatorial identities for some Borcherds superalgebras ^{[4]}.
Contribution
Prof Sthanumoorthy had organized an International Symposium on Kac Moody Algebras in Chennai in 2002 ^{[5]}, attended by Mathematicians across the globe. The proceedings of the International symposium had been released under the topic Kac Moody Lie Algebras in Contemporary Mathematics Series.^{[6]}. He had been a Guest Scientist and had delivered lectures in USA ^{[7]} ^{[8]}, Max Planck Institute Germany ^{[9]}, ICTP Italy, and China. He had guided research assistants during his teaching career ^{[10]}.
Book Written
Prof Sthanumoorthy had authored a book, Introduction to Finite and Infinite Dimensional Lie(Super) Algebras published by Academic Press Elsevier ^{[11]}, in 2015. It has connections with combinatorics, Differential Equations, group theory, modular forms, singularities, knot theory, statistical mechanics, quantum field and string theory. ^{[12]}
Illness and Death
Professor Sthanumoorthy was diagnosed with Pulmonary Fibrosis during the beginning of the year 2018 and after a prolonged illness he passed away in the evening hours on Jan 28, 2020.
