Paul Cohen - WikipediaHe is best known for his proofs that the continuum hypothesis and the axiom of choice are independent from Zermelo—Fraenkel set theory , for which he was awarded a Fields Medal. Cohen next studied at the Brooklyn College from to , 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 and his Doctor of Philosophy degree in , under supervision of Antoni Zygmund. In , before the award of his doctorate, Cohen was appointed as an Instructor in Mathematics at the University of Rochester for a year. He then spent the academic year —59 at the Massachusetts Institute of Technology before spending —61 as a fellow at the Institute for Advanced Study at Princeton. These were years in which Cohen made a number of significant mathematical breakthroughs. In Factorization in group algebras he showed that any integrable function on a locally compact group is the convolution of two such functions, solving a problem posed by Walter Rudin.
