**Helge Arnulf Tverberg** (March 6, 1935 –December 28, 2020) was a Norwegian mathematician. He was a professor in the Mathematics Department at the University of Bergen, his speciality being combinatorics; he retired at the mandatory age of seventy.

He was born in Bergen.^{ [1] } He took the cand.real. degree at the University of Bergen in 1958, and the dr.philos. degree in 1968. He was a lecturer from 1958 to 1971 and professor from 1971 to his retirement in 2005. He was a visiting scholar at the University of Reading in 1966 and at the Australian National University, in Canberra, from 1980 to 1981, 1987 to 1988 and in 2004.^{ [2] } He is a member of the Norwegian Academy of Science and Letters.^{ [3] }

Tverberg, in 1965, proved a result on intersection patterns of partitions of point configurations that has come to be known as Tverberg's partition theorem. It inaugurated a new branch of combinatorial geometry, with many variations and applications. An account by Günter M. Ziegler of Tverberg's work in this direction appeared in the issue of the Notices of the American Mathematical Society for April, 2011.^{ [4] }

The **Abel Prize** is a prize awarded annually by the King of Norway to one or more outstanding mathematicians. It is named after Norwegian mathematician Niels Henrik Abel (1802–1829) and directly modeled after the Nobel Prizes. It comes with a monetary award of 7.5 million Norwegian kroner (NOK).

**Yakov Grigorevich Sinai** is a Russian mathematician known for his work on dynamical systems. He contributed to the modern metric theory of dynamical systems and connected the world of deterministic (dynamical) systems with the world of probabilistic (stochastic) systems. He has also worked on mathematical physics and probability theory. His efforts have provided the groundwork for advances in the physical sciences.

**Bernt Karsten Øksendal** is a Norwegian mathematician. He completed his undergraduate studies at the University of Oslo, working under Otte Hustad. He obtained his PhD from University of California, Los Angeles in 1971; his thesis was titled *Peak Sets and Interpolation Sets for Some Algebras of Analytic Functions* and was supervised by Theodore Gamelin. In 1991, he was appointed as a professor at the University of Oslo. In 1992, he was appointed as an adjunct professor at the Norwegian School of Economics and Business Administration, Bergen, Norway.

**Helge Pharo** is a Norwegian historian.

**Leiv Kristen Sydnes** is a Norwegian chemist, specializing in organic chemistry.

**Edvard Freydar Beyer** was a Norwegian literary historian, literary critic, and professor at the University of Oslo from 1958 to 1990.

**Helge Dahl** was a Norwegian educationalist.

**Kristian Barstad Dysthe** is a Norwegian mathematician.

**Helge Holden** 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.

**John Grue** is a Norwegian applied mathematician noted for his contributions to marine hydrodynamics and internal waves.

**Sigve Tjøtta** is a Norwegian mathematician.

**Jan Mangerud** is a Norwegian geologist who grew up in Lillestrøm, Akershus, and currently lives in Rådal, Bergen.

**Ernst Sejersted Selmer** was a Norwegian mathematician, who worked in number theory, as well as a cryptologist. The Selmer group of an Abelian variety is named after him. His primary contributions to mathematics reside within the field of diophantine equations. He started working as a cryptologist during the Second World War; due to his work, Norway became a NATO superpower in the field of encryption.

**Jonas Ekman Fjeldstad** was a prize-winning Norwegian oceanographer and mathematician.

**Inga Berre** is a Norwegian applied mathematician who studies numerical methods for the partial differential equations used to model fractured geothermal systems and porous media more generally. She is a professor in the department of mathematics at the University of Bergen, a scientific advisor to the Chr. Michelsen Institute in Bergen, and a leading researcher on geothermal energy in Norway.
