**Thomas William Körner** (born 17 February 1946) is a British pure mathematician and the author of school books. He is titular Professor of Fourier Analysis in the University of Cambridge and a Fellow of Trinity Hall. He is the son of the philosopher Stephan Körner and of Edith Körner.

The **United Kingdom of Great Britain and Northern Ireland**, commonly known as the **United Kingdom** (**UK**) or **Britain**, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea separates Great Britain and Ireland. The United Kingdom's 242,500 square kilometres (93,600 sq mi) were home to an estimated 66.0 million inhabitants in 2017.

**Pure mathematics** is the study of mathematical concepts independently of any application outside mathematics. These concepts may originate in real-world concerns, and the results obtained may later turn out to be useful for practical applications, but pure mathematicians are not primarily motivated by such applications. Instead, the appeal is attributed to the intellectual challenge and aesthetic beauty of working out the logical consequences of basic principles.

The **University of Cambridge** is a collegiate public research university in Cambridge, United Kingdom. Founded in 1209 and granted a Royal Charter by King Henry III in 1231, Cambridge is the second-oldest university in the English-speaking world and the world's fourth-oldest surviving university. The university grew out of an association of scholars who left the University of Oxford after a dispute with the townspeople. The two 'ancient universities' share many common features and are often referred to jointly as 'Oxbridge'. The history, influence and wealth of the University of Cambridge has made it one of the most prestigious universities in the world.

He studied at Trinity Hall, Cambridge, and wrote his PhD thesis * Some Results on Kronecker, Dirichlet and Helson Sets* there in 1971, studying under Nicholas Varopoulos.

**Trinity Hall** is a constituent college of the University of Cambridge, England. It is the fifth-oldest college of the university, having been founded in 1350 by William Bateman, Bishop of Norwich.

**Nicholas Theodore Varopoulos** is a Greek mathematician, who works on harmonic analysis and especially analysis on Lie groups.

The **Salem Prize**, founded by the widow of Raphael Salem, is awarded to young mathematicians judged to have done outstanding work in Salem's field of interest, primarily the theory of Fourier series. The prize is considered highly prestigious and many Fields Medalists previously received Salem prize. The prize was 5000 French Francs in 1990.

He has written four academic mathematics books aimed at undergraduates:

*Fourier Analysis*^{ [3] }*Exercises for Fourier Analysis**A Companion to Analysis**Calculus for the Ambitious*

He has also written two books aimed at secondary school students, the popular 1996 title *The Pleasures of Counting* and *Naive Decision Making* (published 2008) on probability, statistics and game theory.

**Trinity College** is a constituent college of the University of Cambridge in England. With around 600 undergraduates, 300 graduates, and over 180 fellows, it is the largest college in either of the Oxbridge universities by number of undergraduates. In terms of total student numbers, it is second only to Homerton College, Cambridge.

**Sir William Timothy Gowers**, is a British mathematician. He is a Royal Society Research Professor at the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge, where he also holds the Rouse Ball chair, and is a Fellow of Trinity College, Cambridge. In 1998, he received the Fields Medal for research connecting the fields of functional analysis and combinatorics.

**Elias Menachem Stein** was an American mathematician, and a leading figure in the field of harmonic analysis. He was professor of Mathematics at Princeton University from 1963 until his death in 2018.

**Charles Louis Fefferman** is an American mathematician at Princeton University. His primary field of research is mathematical analysis.

**Béla Bollobás** FRS is a Hungarian-born British mathematician who has worked in various areas of mathematics, including functional analysis, combinatorics, graph theory, and percolation. He was strongly influenced by Paul Erdős since the age of 14.

**Sir Michael James Lighthill**, was a British applied mathematician, known for his pioneering work in the field of aeroacoustics.

**Ernest William Hobson** FRS was an English mathematician, now remembered mostly for his books, some of which broke new ground in their coverage in English of topics from mathematical analysis. He was Sadleirian Professor of Pure Mathematics at the University of Cambridge from 1910 to 1931.

**Ben Joseph Green** FRS is a British mathematician, specialising in combinatorics and number theory. He is the Waynflete Professor of Pure Mathematics at the University of Oxford.

**Raphaël Salem** (Greek: Ραφαέλ Σαλέμ; November 7, 1898 in Salonika, Ottoman Empire – June 20, 1963 in Paris, France), was a Greek mathematician after whom are named the Salem numbers and Salem–Spencer sets and whose widow founded the Salem Prize.

**Jean-Pierre Kahane** was a French mathematician with contributions to harmonic analysis.

**Stephan Körner**, FBA was a British philosopher, who specialised in the work of Kant, the study of concepts, and in the philosophy of mathematics. Born to a Jewish family in Czechoslovakia, he left the country to avoid certain death at the hands of the Nazis after the German occupation in 1939, and came to the United Kingdom as a refugee, where he began his study of philosophy; by 1952 he was a professor of philosophy at the University of Bristol, taking up a second professorship at Yale in 1970. He was married to Edith Körner, and was the father of the mathematician Thomas Körner and the biochemist, writer and translator (née) Ann M. Körner.

**Victor William Guillemin** is a mathematician working in the field of symplectic geometry, who has also made contributions to the fields of microlocal analysis, spectral theory, and mathematical physics. He is a tenured Professor in the Department of Mathematics at the Massachusetts Institute of Technology.

**Gilles I. Pisier** is a professor of mathematics at the Pierre and Marie Curie University and a distinguished professor and A.G. and M.E. Owen Chair of Mathematics at the Texas A&M University. He is known for his contributions to several fields of mathematics, including functional analysis, probability theory, harmonic analysis, and operator theory. He has also made fundamental contributions to the theory of C*-algebras. Gilles is the younger brother of French actress Marie-France Pisier.

**William Beckner** is an American mathematician, known for his work in harmonic analysis, especially geometric inequalities. He is the Paul V. Montgomery Centennial Memorial Professor in Mathematics at The University of Texas at Austin.

**Christopher Donald Sogge** is an American mathematician. He is the J. J. Sylvester Professor of Mathematics at Johns Hopkins University and the editor-in-chief of the *American Journal of Mathematics*. His research concerns Fourier analysis and partial differential equations.

**Tadashi Tokieda** is a Japanese mathematician, working in mathematical physics. He is a professor of mathematics at Stanford University; previously he was the Director of Studies in Mathematics at Trinity Hall, Cambridge. He is also very active in inventing, collecting, and studying toys that uniquely reveal and explore real-world surprises of mathematics and physics. In comparison with most mathematicians, he had an unusual path in life: he started as a painter, and then became a classical philologist, before switching to mathematics.

The **Princeton University Department of Mathematics** is an academic department at Princeton University. Founded in 1760, the department has trained some of the world's most renowned and internationally recognized scholars of mathematics. Notable individuals affiliated with the department include John Nash, Senior Research Mathematician and winner of the 1994 Nobel Prize; Alan Turing, who received his doctorates from the department; and Albert Einstein who frequently gave lectures at Princeton and had an office in the building.
