Bohuslav Diviš
Bohuslav Diviš (December 20, 1942 – July 26, 1976) was a Czech mathematician, who worked in the field of number theory. Biography Bohuslav Diviš was born on December 20, 1942, in Prague. He won the Czechoslovak and International Mathematical Olympiad in 1959 and then studied mathematics at Charles University in Prague (as a student of Vojtěch Jarník). He wrote his thesis in 1966 and his doctorate in 1969 with a thesis on "superlattice points in multidimensional ellipsoids" at the Heidelberg University under Peter Roquette. In 1970 Diviš became assistant professor at Ohio State University (USA), and after 1973 an associate professor. He authored about 20 scientific articles. On July 26, 1976, during a conference visit to Illinois State University in Normal, Illinois, he died of heart failure at the age of 33. Literature * B.

Number Theory
Number theory is a branch of pure mathematics devoted primarily to the study of the integers and arithmetic functions. Number theorists study prime numbers as well as the properties of mathematical objects constructed from integers (for example, rational numbers), or defined as generalizations of the integers (for example, algebraic integers). Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory can often be understood through the study of Complex analysis, analytical objects, such as the Riemann zeta function, that encode properties of the integers, primes or other number-theoretic objects in some fashion (analytic number theory). One may also study real numbers in relation to rational numbers, as for instance how irrational numbers can be approximated by fractions (Diophantine approximation). Number theory is one of the oldest branches of mathematics alongside geometry. One quirk of number theory is ...

International Mathematical Olympiad
The International Mathematical Olympiad (IMO) is a mathematical olympiad for pre-university students, and is the oldest of the International Science Olympiads. It is widely regarded as the most prestigious mathematical competition in the world. The first IMO was held in Romania in 1959. It has since been held annually, except in 1980. More than 100 countries participate. Each country sends a team of up to six students, plus one team leader, one deputy leader, and observers. Awards are given to approximately the top-scoring 50% of the individual contestants. Teams are not officially recognized—all scores are given only to individual contestants, but team scoring is unofficially compared more than individual scores. Question type The content ranges from extremely difficult algebra and pre-calculus problems to problems in branches of mathematics not conventionally covered in secondary or high school and often not at university level either, such as projective and complex geo ...

Charles University
Charles University (CUNI; , UK; ; ), or historically as the University of Prague (), is the largest university in the Czech Republic. It is one of the List of oldest universities in continuous operation, oldest universities in the world in continuous operation, the oldest university north of the Alps and east of University of Paris, Paris. Today, the university consists of 17 faculties located in Prague, Hradec Králové, and Plzeň. History Medieval university (1349–1419) The establishment of a medieval university in Prague was inspired by Holy Roman Emperor Charles IV, Holy Roman Emperor, Charles IV. He requested his friend and ally, Pope Clement VI, to create the university. On 26 January 1347, the pope issued the bull establishing a university in Prague, modeled on the University of Paris, with all four faculty (division), faculties, including theology. On 7 April 1348 Charles, the king of Bohemia, gave to the established university privileges and immunities from the se ...

Vojtěch Jarník
Vojtěch Jarník (; 22 December 1897 – 22 September 1970) was a Czech mathematician. He worked for many years as a professor and administrator at Charles University, and helped found the Czechoslovak Academy of Sciences. He is the namesake of Jarník's algorithm for minimum spanning trees. Jarník worked in number theory, mathematical analysis, and graph algorithms. He has been called "probably the first Czechoslovak mathematician whose scientific works received wide and lasting international response". As well as developing Jarník's algorithm, he found tight bounds on the number of lattice points on convex curves, studied the relationship between the Hausdorff dimension of sets of real numbers and how well they can be approximated by rational numbers, and investigated the properties of nowhere-differentiable functions. Education and career Jarník was born on 22 December 1897. He was the son of , a professor of Romance language philology at Charles University, and his ...

Peter Roquette
Peter Jaques Roquette (8 October 1927 – 24 February 2023) was a German mathematician working in algebraic geometry, algebra, and number theory. Biography Roquette was born in Königsberg on 8 October 1927. He studied in Erlangen, Berlin, and Hamburg. In 1951 he defended a dissertation at the University of Hamburg under Helmut Hasse, providing a new proof of the Riemann hypothesis for algebraic function fields over a finite field (the first proof was given by André Weil in 1940). In 1951/1952 he was an assistant at the Mathematical Research Institute at Oberwolfach and from 1952 to 1954 at the University of Munich. From 1954 to 1956 he worked at the Institute for Advanced Study in Princeton. In 1954 he was Privatdozent at Munich, and from 1956 to 1959 he worked in the same position at Hamburg.
