mathematician 1938 1974 not to be confused with srinivasa ramanujan c p ramanujam born chidambaram padmanabhan ramanujam 9 january 1938 madras madras presidency british india died 27 october 1974 age 36 bangalore india education loyola college madras tata institute of fundamental research awards fellow indian academy of sciences scientific career fields mathematics workplaces tata institute of fundamental research doctoral advisor k g ramanathan chidambaram padmanabhan ramanujam 9 january 1938 27 october 1974 was an indian mathematician who worked in the fields of number theory and algebraic geometry he was elected a fellow of the indian academy of sciences in 1973 as david mumford put it ramanujam felt that the spirit of mathematics demanded of him not merely routine developments but the right theorem on any given topic he wanted mathematics to be beautiful and to be clear and simple he was sometimes tormented by the difficulty of these high standards but in retrospect it is clear to us how often he succeeded in adding to our knowledge results both new beautiful and with a genuinely original stamp 1 early life and education edit chidambaram padmanabhan ramanujam was born to a tamil family on 9 january 1938 in madras now chennai india as the eldest of seven to chakravarthi srinivasa padmanabhan 2 he finished his schooling in town higher secondary school kumbakonam and joined loyola college in madras in 1952 he wanted to specialise in mathematics and he set out to master it with vigour and passion he also enjoyed music and his favourite musician was m d ramanathan a maverick concert musician his teacher and friend at this time was father fr charles racine 1897 1976 loyola college a missionary who had obtained his doctorate under the supervision of élie cartan he had been taught mathematics by father charles racine in his final honours years at loyola college and he encouraged ramanujam to apply for entry to the school of mathematics at the tata institute in bombay in his letter of recommendation father charles racine wrote he has certainly originality of mind and the type of curiosity which is likely to suggest that he will develop into a good research worker if given sufficient opportunity with father charles racine s encouragement and recommendation ramanujam applied and was admitted to the graduate school at the tata institute of fundamental research in bombay his father had wanted him to join the indian statistical institute in calcutta as he had passed the entrance exam meritoriously 3 career edit ramanujam set out for mumbai at the age of eighteen to pursue his interest in mathematics he and his friend and schoolmate raghavan narasimhan and s ramanan joined tifr together in 1957 at the tata institute there was a stream of first rate visiting mathematicians from all over the world it was a tradition for some graduate student to write up the notes of each course of lectures accordingly ramanujam wrote up in his first year the notes of max deuring s lectures on algebraic functions of one variable it was a nontrivial effort and the notes were written clearly and were well received the analytical mind was much in evidence in this effort as he could simplify and extend the notes within a short time period he could reduce difficult solutions to be simple and elegant due to his deep knowledge of the subject matter states ramanan max deuring s lectures gave him a taste for algebraic number theory he studied not only algebraic geometry and analytic number theory of which he displayed a deep knowledge but he became an expert in several other allied subjects as well on the suggestion of his doctoral advisor k g ramanathan he began working on a problem relating to the work of the german number theorist carl ludwig siegel in the course of proving the main result to the effect that every cubic form in 54 variables over any algebraic number field k had a non trivial zero over that field he had also simplified the earlier method of siegel he took up waring s problem in algebraic number fields and got interesting results in recognition of his work and his contribution to number theory the institute promoted him to associate professor he protested against this promotion as undeserved and had to be persuaded to accept the position he proceeded to write his thesis in 1966 and took his doctoral examination in 1967 dr siegel who was one of the examiners was highly impressed with the young man s depth of knowledge and his great mathematical abilities ramanujam was a scribe for igor shafarevich s course of lectures in 1965 on minimal models and birational transformation of two dimensional schemes professor shafarevich subsequently wrote to say that ramanujam not only corrected his mistakes but complemented the proofs of many results the same was the case with mumford s lectures on abelian varieties which were delivered at tifr around 1967 mumford wrote in the preface to his book that the notes improved upon his work and that his current work on abelian varieties was a joint effort between him and ramanujam during this time he started teaching himself german italian russian and french so that he could study mathematical works in their original form his personal library contained quite a few non english mathematical works in 1978 tifr published a tribute for c p ramanujam springer verlag publication https x com naa_ganesan status 2045374322978545922 illness and death edit between 1964 and 1968 he was making great strides in number theory and his contacts with shafarevich and mumford led him on to algebraic geometry according to ramanathan and other colleagues his progress and deep understanding of algebraic geometry was phenomenal in 1964 based on his participation in the international colloquium on differential analysis he earned the respect of alexander grothendieck and of david mumford who invited him to paris and harvard he accepted the invitation and was in paris but for a brief period he was diagnosed in 1964 with schizophrenia with severe depression and left paris for chennai he later decided to quit his position at tifr he quit his post at mumbai in 1965 after a bout of illness and secured a tenured position as a professor in chandigarh punjab there he met the young student chitikila musili who later went on to prove interesting results in the geometry connected with the theory of lie groups and wrote good expository books ramanujam stayed in chandigarh only eight months and he had to return to chennai again for treatment tifr was his real home and he was back there again in june 1965 around this time he accepted an invitation from institut des hautes études scientifiques near paris he was barely there before he was flown back to chennai unfortunately schizophrenia a highly treatable condition today was not properly diagnosed and treated at that time thus he continued until the end of his life to be highly creative for short periods before the recurrent illness overtook him again in 1970 he sent his resignation letter to tifr but the institute would not take it seriously around this time mumford invited him to warwick as a visiting professor during the algebraic geometry year mumford writes that he spent many delightful evenings with ramanujam and that his presence contributed importantly to the success of the algebraic geometry year a famous paper written during this time by michael artin and david mumford acknowledges ramanujam s suggestions and help he also had a short tenure at turin where he was widely appreciated and accepted just after his death a commemorative hall was named after him in the former istituto di matematica institute of mathematics of the university of genoa back in india after his year at the university of warwick ramanujam requested for a professorship at the tata institute but to be made tenable in their bangalore campus the tata institute had an applied mathematics wing in bangalore although ramanjuam had nothing to do with this area the institute wishing him to continue his research made a special arrangement by which he could stay and work there by this time he was deeply affected and depressed by his illness he was put in charge of a new branch dealing with applied mathematics he settled down in bangalore but again in the depths of depression caused by his illness he tried to leave the institute and obtain a university teaching post during one of the attacks he tried to take his life but was rescued in time however late one evening on 27 october 1974 after a lively discussion with a visiting foreign professor he took his life with an overdose of barbiturates see also edit ramanujam samuel theorem ramanujam vanishing theorem notes edit
