Adam Harper is awarded the 2019 SASTRA Ramanujan Prize for several outstanding contributions to analytic and probabilisticnumber theory. The prizerecognizeshis marvellous 2012 Ph. D. thesis at CambridgeUniversity, and his paper of 2013 in Crelle's Journal in which, among other things, he disproved a widely believed conjecture on the normal distribution of partial sums of random multiplicative functions by novel use of deep probabilistic methods. The prize also recognizes Harper's recent brilliant proof of aconjectureofHelson that the partial sums have better than square-root cancellation using ideas on multiplicative chaos, and arelated paper on higher moments of random multiplicative functions to appear in Algebra and Number Theory. Harper's seminal work using the Riemann Hypothesis to determine the correct order upper bound for the higher moments of the Riemann zeta function on the critical line is an outstanding contribution to the Pield. The prize also notes that Harper proved the upper bound part of aconjectureofFyodorov, Hiary and Keating on the almost always maximum sizeof the Riemannzeta function in short intervalson the criticalline. The prizerecognizes Harper's ingenious work on S-unit equations and related results for these equations over smooth numbers that signiPicantly improves earlier important work of Konyagin and Soundararajan. The prize notes that in his 2012 Journal of Number Theory paper, Harper established certain conjecturesof Soundararajan on the equi-distribution of smooth numbers, and morerecently that Harper has established apowerful Bombieri- Vinogradovtype theorem for smooth numbers. In addition, the prizerecognizes Harper's novelproof of a famous theorem of Halasz, that led to two major joint papers on the “pretentious approachto number theory” with AndrewsGranville and Kannan Soundararajan in Compositio Math.

He also placed on record the fact that Warwick, England, the winner of SASTRA Ramanujan the University’s initiative has been recognized by The Award for the year 2019 delivered the Srinivasa Royal Society in a paper titled “Ramanujan’s Legacy: Ramanujan Commemorative Lecture on December 22, The Work of the SASTRA Prize Winners.” 2019. He spoke on the topic Probability, Ramanujan and Analytic Number Theory. Probabilistic number theory means the application of probabilistic ideas, viewpoints and methods to solve number theoretical problems. It is generally said to have begun in the work of Hardy and Ramanujan in 1917, who showed that a ‘typical’ natural number ‘n’ always has around log ‘n’ prime divisors. Adam Harper explained this result, and gave an idea of how new probabilistic ideas are influencing work in analytic number theory up to the present day. 17TH INTERNATIONAL CONFERENCE ON NUMBER THEORY Prof. Krishnaswami Alladi, University of Florida, USA, The 17th International Conference on Number Chairman, SASTRA-Ramanujan Award Committee Theory was inaugurated by Prof. Ken Ono, Thomas read out the Citation of Dr. Adam Harper.

  • Sastra Prize 2005
    UF SASTRA PRIZE Mathematics 2005 Research Courses Undergraduate Graduate News Resources People BHARGAVA AND SOUNDARARAJAN TO RECEIVE THE FIRST SASTRA RAMANUJAN PRIZE The 2005 SASTRA Ramanujan Prize will be jointly awarded to Professors MANJUL BHARGAVA (Princeton University) and KANNAN SOUNDARARAJAN (University of Michigan). This annual prize, being awarded for the first time, is for outstanding contributions by individuals not exceeding the age of 32 in areas of mathematics influenced by Ramanujan in a broad sense. The age limit was set at 32 because Ramanujan achieved so much in his brief life of 32 years. The $10,000 prize will be awarded annually in December at the Srinivasa Ramanujan Centre of SASTRA University in Ramanujan's hometown, Kumbakonam, South India. MANJUL BHARGAVA has made phenomenal contributions to number theory, most notably by his discovery of higher order composition laws. This is his PhD thesis, written under the direction of Professor Andrew Wiles of Princeton University and published as a series of papers in the Annals of Mathematics. Gauss, the Prince of Mathematicians, constructed a law of composition for binary quadratic forms. Bhargava introduced entirely new and unexpected ideas that led to his discovery of such composition laws for forms of higher degree. Bhargava then applied these composition laws to solve a new case of one of the fundamental questions of number theory, that of the asymptotic enumeration of number fields of a given degree d. The question is trivial for d=1, and Gauss himself solved the case d=2 in 1801. Then in 1971 Davenport and Heilbronn solved the d=3 case.

  • After Ramanujan Left Us– a Stock-Taking Exercise S
    Ref: after-ramanujanls.tex Ver. Ref.: : 20200426a After Ramanujan left us– a stock-taking exercise S. Parthasarathy [email protected] 1 Remembering a giant This article is a sequel to my article on Ramanujan [14]. April 2020 will mark the death centenary of the legendary Indian mathe- matician – Srinivasa Ramanujan (22 December 1887 – 26 April 1920). There will be celebrations of course, but one way to honour Ramanujan would be to do some introspection and stock-taking. This is a short survey of notable achievements and contributions to mathematics by Indian institutions and by Indian mathematicians (born in India) and in the last hundred years since Ramanujan left us. It would be highly unfair to compare the achievements of an individual, Ramanujan, during his short life span (32 years), with the achievements of an entire nation over a century. We should also consider the context in which Ramanujan lived, and the most unfavourable and discouraging situation in which he grew up. We will still attempt a stock-taking, to record how far we have moved after Ramanujan left us. Note : The table below should not be used to compare the relative impor- tance or significance of the contributions listed there. It is impossible to list out the entire galaxy of mathematicians for a whole century. The table below may seem incomplete and may contain some inad- vertant errors.

  • Weak Subconvexity for Central Values of L-Functions
    ANNALS OF MATHEMATICS Weak subconvexity for central values of L-functions By Kannan Soundararajan SECOND SERIES, VOL. 172, NO. 2 September, 2010 anmaah Annals of Mathematics, 172 (2010), 1469–1498 Weak subconvexity for central values of L-functions By KANNAN SOUNDARARAJAN Abstract We describe a general method to obtain weak subconvexity bounds for many classes of L-functions. We give several examples of our bound, and our work has applications to a conjecture of Rudnick and Sarnak for the mass equidistribution of Hecke eigenforms 1. Introduction and statement of results A fundamental problem in number theory is to estimate the values of L- functions at the center of the critical strip. The Langlands program predicts that all L-functions arise from automorphic representations of GL.N / over a number field, and moreover that such L-functions can be decomposed as a product of primitive L-functions arising from irreducible cuspidal representations of GL.n/ over Q. The L-functions that we consider will either arise in this manner, or will be the Rankin-Selberg L-function associated to two irreducible cuspidal representations. Note that such Rankin-Selberg L-functions are themselves expected to arise from automorphic representations, but this is not known in general. Given an irreducible cuspidal automorphic representation (normalized to have unitary central character), we denote the associated standard L-function by L.s; /, and its analytic conductor (whose definition we shall recall shortly) by 1 1 " C./. There holds generally a convexity bound of the form L. ; / " C./ 4 2 C (see Molteni [28]).1 The Riemann hypothesis for L.s; / implies the Lindelof¨ hypothesis: L.

This annual prize which was established in 2005, is for outstanding contributions by very young mathematicians to areas influenced by the genius Srinivasa Ramanujan. The age limit for the prize has been set at 32 because Ramanujan achieved so much in his brief life of 32 years. The $10,000 prize will be awarded at the International Conference on Number Theory, Ergodic Theory and Dynamics at SASTRA University in Kumbakonam, India (Ramanujan's hometown) on December 22, Ramanujan's birthday. Dr. Roman Holowinsky has made very significant contributions to areas which are at the interface of analytic number theory and the theory of modular forms. Along with Professor Kannan Soundararajan of Stanford University (winner of the SASTRA Ramanujan Prize in 2005), Dr. Holowinsky solved an important case of the famous Quantum Unique Ergodicity (QUE) Conjecture in 2008. This is a spectacular achievement. In 1991, Zeev Rudnick and Peter Sarnak formulated the QUE Conjecture which in its general form concerns the correspondence principle for quantizations of chaotic systems. One aspect of the problem is to understand how waves are influenced by the geometry of their enclosure. Rudnick and Sarnak conjectured that for sufficiently chaotic systems, if the surface has negative curvature, then the high frequency quantum wave functions are uniformly distributed within the domain.

    UF SASTRA PRIZE Mathematics 2010 Research Courses Undergraduate Graduate News Resources People WEI ZHANG TO RECEIVE 2010 SASTRA RAMANUJAN PRIZE The 2010 SASTRA Ramanujan Prize will be awarded to Wei Zhang, who is now a Benjamin Pierce Instructor at the Department of Mathematics, Harvard University, USA. This annual prize which was established in 2005, is for outstanding contributions by very young mathematicians to areas influenced by the genius Srinivasa Ramanujan. The age limit for the prize has been set at 32 because Ramanujan achieved so much in his brief life of 32 years. The $10,000 prize will be awarded at the International Conference on Number Theory and Automorphic Forms at SASTRA University in Kumbakonam, India (Ramanujan's hometown) on December 22, Ramanujan's birthday. Dr. Wei Zhang has made far reaching contributions by himself and in collaboration with others to a broad range of areas in mathematics including number theory, automorphic forms, L-functions, trace formulas, representation theory and algebraic geometry. We highlight some of his path-breaking contributions: In 1997, Steve Kudla constructed a family of cycles on Shimura varieties and conjectured that their generating functions are actually Siegel modular forms. The proof of this conjecture for Kudla cycles of codimension 1 is a major theorem of the Fields Medalist Borcherds. In his PhD thesis, written under the direction of Professor Shou Wu Zhang at Columbia University, New York, Wei Zhang established conditionally, among other things, a generalization of the results of Borcherds to higher dimensions, and in that process essentially settled the Kudla conjecture. His thesis, written when he was just a second year graduate student, also extended earlier fundamental work of Hirzebruch-Zagier and of Gross-Kohnen- Zagier.
