Helge Holden (born 28 September 1956) is a Norwegian mathematician working in the field of differential equations and mathematical physics. He was Praeses of the Royal Norwegian Society of Sciences and Letters from 2014 to 2016.
He earned the dr.philos. degree at the University of Oslo in 1985. The title of his dissertation with Raphael Høegh-Krohn was Point Interactions and the Short-Range Expansion. A Solvable Model in Quantum Mechanics and Its Approximation. He was appointed professor at the Norwegian Institute of Technology (now: the Norwegian University of Science and Technology ) in 1991. His research interests are Differential equations, mathematical physics (in particular hyperbolic conservation laws and completely integrable systems), Stochastic analysis, and flow in porous media.
In 2014 he became Chairman of the board of the Abel Prize fund.He was elected Secretary General of the International Mathematical Union (IMU) for the period 2019–2022.

Dan Laksov (10 July 1940 – 25 October 2013) was a Norwegian-Swedish mathematician and human rights activist. He was primarily active within the field of algebraic geometry.

Jefferson Antonio Galves (18 June 1947 – 5 September 2023) was a Brazilian mathematician, professor of the Institute of Mathematics and Statistics of the University of São Paulo (USP) and member of the Brazilian Academy of Sciences. His field of studies was related to statistical models, in particular models that have stochasticity and variable range of memory. Galves was also the leader of NeuroMat, a research center established in 2013 at USP that is dedicated to integrating mathematical modeling and theoretical neuroscience.

Sidney Michael Dancoff (September 27, 1913 in Philadelphia – August 15, 1951 in Urbana, Illinois) was an American theoretical physicist best known for the Tamm–Dancoff approximation method and for nearly developing a renormalization method for solving quantum electrodynamics (QED).

Francis William Lawvere (; February 9, 1937 – January 23, 2023) was an American mathematician known for his work in category theory, topos theory and the philosophy of mathematics.

Joaquín Bustoz Jr. (1939–2003) was an American mathematician who worked as a professor of mathematics at Arizona State University. His mathematical research concerned functional analysis, including orthogonal polynomials and special functions, but he was primarily known as a mentor to underrepresented minorities in mathematics.Bustoz was born in Tempe, Arizona; his parents worked on the local farms and also for the Tempe Elementary School District, which eventually named the Joaquin and Ramona Bustoz Elementary School after them. He graduated from Arizona State University in 1962 with a degree in mathematics, and after two years in California working for Univac returned to ASU, where he completed a doctorate in 1967 under the supervision of Walter Tandy Scott. After teaching at the University of Cincinnati from 1969 to 1976, during which he also spent a year at the National University of Colombia as a Fulbright Scholar, he returned to ASU again as an associate professor in 1976, and was promoted to full professor in 1978. He chaired the ASU mathematics department from 1982 to 1985.In 1985, Bustoz founded the Summer Math–Science Honors program for high school students, which continues at ASU as the Joaquin Bustoz Math–Science Honors Program. Bustoz also worked on mathematics education on the Navajo Nation and the Pima reservations. For his efforts, president Bill Clinton honored him in 1996 with the Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring.He was killed by a car accident on August 13, 2003. As well as the Math–Science Honors program, the Joaquin Bustoz Jr. Professorship at ASU, held by Carlos Castillo-Chavez, is named after Bustoz.

Arne Bernhard Sletsjøe (sometimes shown as Arne Slettsjø, born 8 April 1960) is a Norwegian mathematician and retired canoe sprinter who competed internationally in the mid to late 1980s.
He won two medals in the K-4 10000 m event at the ICF Canoe Sprint World Championships with a gold in 1987 and a silver in 1983. Sletsjøe also competed in two Summer Olympics in the K-4 1000 m event. At the 1984 Summer Olympics in Los Angeles, he was eliminated in the semifinals. Four years later in Seoul, Sletsjøe and his teammates made the semifinals, but did not finish. Sletsjøe later served as president of the Norwegian Canoe/ Kayak Federation.
He finished his secondary education at Oslo Cathedral School in 1977, graduated from the University of Oslo with the cand.real. degree in 1983 and took the doctorate in 1989. His academic advisor was Arnfinn Laudal. Sletsjøe still works at the university as an associate professor, having started out as a research fellow.He is a son of violist Arne Sletsjøe. He is married to Ingeborg Rasmussen, has two children and resides at Jar.

Ragni Piene (born 18 January 1947, Oslo) is a Norwegian mathematician, specializing in algebraic geometry, with particular interest in enumerative results and intersection theory.

Ola Bratteli (24 October 1946 – 8 February 2015) was a Norwegian mathematician.
He was a son of Trygve Bratteli and Randi Bratteli (née Larssen). He received a PhD degree in 1974. He was appointed as professor at the University of Trondheim in 1980 and at the University of Oslo in 1991. He was a member of the Norwegian Academy of Science and Letters.

Allen Edward Hatcher (born October 23, 1944) is an American topologist.
