Arxiv:2107.06030V2 [Math.HO] 18 Jul 2021 Jonathan Michael Borwein
Jonathan Michael Borwein 1951 { 2016: Life and Legacy Richard P. Brent∗ Abstract Jonathan M. Borwein (1951{2016) was a prolific mathematician whose career spanned several countries (UK, Canada, USA, Australia) and whose many interests included analysis, optimisation, number theory, special functions, experimental mathematics, mathematical finance, mathematical education, and visualisation. We describe his life and legacy, and give an annotated bibliography of some of his most significant books and papers. 1 Life and Family Jonathan (Jon) Michael Borwein was born in St Andrews, Scotland, on 20 May 1951. He was the first of three children of David Borwein (1924{2021) and Bessie Borwein (n´eeFlax). It was an itinerant academic family. Both Jon's father David and his younger brother Peter Borwein (1953{2020) are well-known mathematicians and occasional co-authors of Jon. His mother Bessie is a former professor of anatomy. The Borweins have an Ashkenazy Jewish background. Jon's father was born in Lithuania, moved in 1930 with arXiv:2107.06030v4 [math.HO] 15 Sep 2021 his family to South Africa (where he met his future wife Bessie), and moved with Bessie to the UK in 1948. There he obtained a PhD (London) and then a Lectureship in St Andrews, Scotland, where Jon was born and went to school at Madras College. The family, including Jon and his two siblings, moved to Ontario, Canada, in 1963. In 1971 Jon graduated with a BA (Hons ∗Mathematical Sciences Institute, Australian National University, Canberra, ACT. Email: <[email protected]>. 1 Math) from the University of Western Ontario. It was in Ontario that Jon met his future wife and lifelong partner Judith (n´eeRoots). -
Jonathan Borwein, Pi and the AGM
Jonathan Borwein, Pi and the AGM Richard P. Brent Australian National University, Canberra and CARMA, University of Newcastle 26 Sept 2017 In fond memory of Jon Borwein 1951–2016 210eπ days was not enough Copyright c 2017, R. P. Brent Richard Brent Jon Borwein, π and the AGM Abstract We consider some of Jon Borwein’s contributions to the high-precision computation of π and the elementary functions, with particular reference to the fascinating book Pi and the AGM (Wiley, 1987) by Jon and his brother Peter Borwein. Here “AGM” is the arithmetic-geometric mean, first studied by Euler, Gauss and Legendre. Because the AGM has second-order convergence, it can be combined with fast multiplication algorithms to give fast algorithms for the n-bit computation of π, and more generally the elementary functions. These algorithms run in “almost linear” time O(M(n) log n), where M(n) is the time for n-bit multiplication. The talk will survey some of the results and algorithms, from the time of Archimedes to the present day, that were of interest to Jon. In several cases they were discovered or improved by him. Jon Borwein, π and the AGM Abstract A message from Peter Borwein Peter Borwein writes: “I would’ve loved to attend. But unfortunately I have multiple sclerosis. It makes it impossible to travel. If you could pass on my regards and best wishes to everyone I would greatly appreciate it. Thank you” Jon Borwein, π and the AGM A message from Peter Why π? Why was Jon interested in π? Perhaps because it is transcendental but appears in many mathematical formulas. -

Ch3.3, 3.10 (Small gaps)and then all the Linnik stuff to be cleaned up; i.e. all of chapter 4. Sort out 5.6, 5.7 and chapter 6 ! Riemann's seminal 1860 memoir showed how questions on the distribution of prime numbers are more-or-less equivalent to questions on the distribution of zeros of the Riemann zeta function. This was the starting point for the beautiful theory which is at the heart of analytic number theory. Until now there has been no other coherent approach that was capable of addressing all of the central issues of analytic number theory. In this book we present the pretentious view of analytic number theory; allowing us to recover the basic results of prime number theory without use of zeros of the Riemann zeta-function and related L-functions, and to improve various results in the literature. This approach is certainly more flexible than the classical approach since it allows one to work on many questions for which L-function methods are not suited. However there is no beautiful explicit formula that promises to obtain the strongest believable results (which is the sort of thing one obtains from the Riemann zeta-function). So why pretentious? • It is an intellectual challenge to see how much of the classical theory one can reprove without recourse to the more subtle L-function methodology (For a long time, top experts had believed that it is impossible is prove the prime number theorem without an analysis of zeros of analytic continuations. -
