Not to be confused with Paul Cohn. Paul Joseph Cohen (April 2, 1934 – March 23, 2007) was an American mathematician.

He graduated in 1950, at age 16, from Stuyvesant High School in New York City. Cohen next studied at the Brooklyn College from 1950 to 1953, but he left without earning his bachelor's degree when he learned that he could start his graduate studies at the University of Chicago with just two years of college.

At Chicago, Cohen completed his master's degree in mathematics in 1954 and his Doctor of Philosophy degree in 1958, under supervision of Antoni Zygmund.

He was awarded the Bôcher Memorial Prize in mathematical analysis in 1964 for his paper "On a conjecture by Littlewood and idempotent measures", and lends his name to the Cohen–Hewitt factorization theorem. Cohen was a full professor of mathematics at Stanford University.

In this sense, the continuum hypothesis is undecidable, and it is the most widely known example of a natural statement that is independent from the standard ZF axioms of set theory. For his result on the continuum hypothesis, Cohen won the Fields Medal in mathematics in 1966, and also the National Medal of Science in 1967.

Reading your proof had a similarly pleasant effect on me as seeing a really good play." ===Continuum hypothesis=== While studying the continuum hypothesis, Cohen is quoted as saying in 1985 that he had "had the feeling that people thought the problem was hopeless, since there was no new way of constructing models of set theory.

The title of his doctoral thesis was Topics in the Theory of Uniqueness of Trigonometrical Series. On June 2, 1995 Cohen received an honorary doctorate from the Faculty of Science and Technology at Uppsala University, Sweden. ==Career== Cohen is noted for developing a mathematical technique called forcing, which he used to prove that neither the continuum hypothesis (CH) nor the axiom of choice can be proved from the standard Zermelo–Fraenkel axioms (ZF) of set theory.

Cohen died on March 23, 2007 in Stanford, California after suffering from lung disease. ==Selected publications== ==See also== Cohen algebra ==References== ==Further reading== Akihiro Kanamori, "Cohen and Set Theory", The Bulletin of Symbolic Logic, Volume 14, Number 3, Sept.

The Fields Medal that Cohen won continues to be the only Fields Medal to be awarded for a work in mathematical logic, as of 2018. Apart from his work in set theory, Cohen also made many valuable contributions to analysis.
