N. G. W. H. Beeger
Nicolaas George Wijnand Henri Beeger (1884, in Utrecht – 1965, in Amsterdam) was a Dutch mathematician. His 1916 doctorate was on Dirichlet series. He worked for most of his life as a teacher, working on mathematics papers in his spare evenings. After his retirement as a teacher at 65, he began corresponding with many contemporary mathematicians and dedicated himself to his work. He is known for having proved that 3511 is a Wieferich prime in 1922 and for introducing the term Carmichael number in 1950. Beeger Lecture In 1989 the board of trustees of the Mathematical Centre in Amsterdam established the Beeger lectures, in honor of N.G.W.H. Beeger, to be held biannually at the congress of the Royal Dutch Mathematical Society. Their purpose is to promote research and exchange of ideas in the field of algorithmic and computational number theory. The first Beeger Lecture was delivered in 1992. * 2024 Andrew Sutherland * 2022 Shafi Goldwasser * 2021 David Harvey * 2018 Fern ...

Luigi Poletti (mathematician)
Luigi Poletti (31 December 1864 – 10 March 1967) was an Italian mathematician and poet. He was born in Pontremoli, where he also died, age 102. He attended the episcopal seminary in Potremoli, then the high school of Parma, graduated in Turin and started to study mathematics there. He did not finish and took a job in a bank. 1911 he accidentally found the book of prime number tables written by Lehmer, a mathematician from the United States in the house of professor Gino Loria, a friend of his family, when he visited Genoa. Since then he spent many years to extend the first table in order to simplify "Eratosthenes Crivello" (sieve of Eratosthenes), a method from ancient Greece to find prime numbers. He gave his method a new name: "Neocribrum" (Novum Eratosthenes Cribrum) and he got recognition from the scientific community. Apart from that, he was, together with André Gerardin, member of a study commission of the Association française pour l'avancement des sciences (1946 ...

Yakov Kulik
Jakob Philipp Kulik (1793–1863) was an Austrian mathematician known for his construction of a massive Factor table, factor tables. Biography Kulik was born in Lemberg, which was part of the Austrian Empire, Austrian empire, and is now Lviv located in Ukraine. Kulik's factor tables In 1825, Kulik mentioned a table of factors up to 30 million, but this table does no longer seem to exist. It is also not clear if it had really been completed. From about 1825 until 1863 Kulik produced a factor table of numbers up to 100330200 (except for numbers divisible by 2, 3, or 5). This table basically had the same format as the table to 30 million and it is therefore most likely that the work on the "Magnus canon divisorum" spanned from the mid-1820s to Kulik's death, at which time the tables were still unfinished. These tables fill eight volumes totaling 4212 pages, and are kept in the archives of the Vienna Academy of Sciences, Academy of Sciences in Vienna. Volume II of the 8-volume se ...

Carl Pomerance
Carl Bernard Pomerance (born 1944 in Joplin, Missouri) is an American number theorist. He attended college at Brown University and later received his Ph.D. from Harvard University in 1972 with a dissertation proving that any odd perfect number has at least seven distinct prime factors. He joined the faculty at the University of Georgia, becoming full professor in 1982. He subsequently worked at Lucent Technologies for a number of years, and then became a distinguished professor at Dartmouth College. Contributions He has over 120 publications, including co-authorship with Richard Crandall of ''Prime numbers: a computational perspective'' (Springer-Verlag, first edition 2001, second edition 2005), and with Paul Erdős. He is the inventor of one of the integer factorization methods, the quadratic sieve algorithm, which was used in 1994 for the factorization of RSA-129. He is also one of the discoverers of the Adleman–Pomerance–Rumely primality test. Awards and honors He h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hugh C
Hugh is the English-language variant of the masculine given name , itself the Old French variant of '' Hugo (name)">Hugo'', a short form of Continental Germanic Germanic name">given names beginning in the element "mind, spirit" (Old English ). The Germanic name is on record beginning in the 8th century, in variants ''Chugo, Hugo, Huc, Ucho, Ugu, Uogo, Ogo, Ougo,'' etc. The name's popularity in the Middle Ages ultimately derives from its use by Frankish nobility, beginning with Duke of the Franks and Count of Paris Hugh the Great (898–956). The Old French form was adopted into English from the Norman period (e.g. Hugh of Montgomery, 2nd Earl of Shrewsbury d. 1098; Hugh d'Avranches, 1st Earl of Chester, d. 1101). The spelling ''Hugh'' in English is from the Picard variant spelling '' Hughes'', where the orthography ''-gh-'' takes the role of ''-gu-'' in standard French, i.e. to express the phoneme /g/ as opposed to the affricate /ʒ/ taken by the grapheme ''g'' before front ...

John Conway
John Horton Conway (26 December 1937 – 11 April 2020) was an English mathematician. He was active in the theory of finite groups, knot theory, number theory, combinatorial game theory and coding theory. He also made contributions to many branches of recreational mathematics, most notably the invention of the cellular automaton called the Game of Life. Born and raised in Liverpool, Conway spent the first half of his career at the University of Cambridge before moving to the United States, where he held the John von Neumann Professorship at Princeton University for the rest of his career. On 11 April 2020, at age 82, he died of complications from COVID-19. Early life and education Conway was born on 26 December 1937 in Liverpool, the son of Cyril Horton Conway and Agnes Boyce. He became interested in mathematics at a very early age. By the time he was 11, his ambition was to become a mathematician. After leaving sixth form, he studied mathematics at Gonville and Caius Colleg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peter Borwein
Peter Benjamin Borwein (born St. Andrews, Scotland, May 10, 1953 – 23 August 2020) was a Canadian mathematician and a professor at Simon Fraser University. He is known as a co-author of the paper which presented the Bailey–Borwein–Plouffe algorithm (discovered by Simon Plouffe) for computing π. First interest in mathematics Borwein was born into a Jewish family. He became interested in number theory and classical analysis during his second year of university. He had not previously been interested in math, although his father was the head of the University of Western Ontario's mathematics department and his mother is associate dean of medicine there. Borwein and his two siblings majored in mathematics. Academic career After completing a Bachelor of Science in Honours Math at the University of Western Ontario in 1974, he went on to complete an MSc and Ph.D. at the University of British Columbia.
