John Friedlander
John Benjamin Friedlander is a Canadian mathematician who specializes in analytic number theory. He earned a B.Sc. from the University of Toronto in 1965, an M.A. from the University of Waterloo in 1966, and a Ph.D. from Pennsylvania State University in 1972. He was a lecturer at MIT from 1974 to 1976 and has been on the faculty of the University of Toronto since 1977, serving as chair from 1987 to 1991. He has spent time at the Institute for Advanced Study. He is known for his collaboration with Enrico Bombieri, William Duke, Andrew Granville, and especially Henryk Iwaniec, and for the Bombieri–Friedlander–Iwaniec theorem in analytic number theory. In 1997, with Iwaniec, he proved that there are infinitely many prime numbers that can be written as the sum of a square and a fourth power: a^2 + b^4. They extended Enrico Bombieri’s asymptotic sieve to achieve this result. Friedlander is a Fellow of the Royal Society of Canada, has received the Jeffery–Williams Prize, and became a Fellow of the American Mathematical Society in 2012.
