Lennart Carleson

Professor Lennart Carleson ForMemRS

Foreign Member

Elected: 1993


Lennart Carleson is a world-leading mathematician who has made fundamental contributions to a branch of mathematics known as harmonic analysis. His research highlights include demonstrating the almost everywhere convergence of Fourier series for square-integrable functions, as well as contributions to the corona theorem.

Through his work on the corona theorem, he was able to develop the theory of Carleson measures, which has become a useful tool for modern function theory. Alongside his research, Lennart has served as both Editor of the distinguished journal Acta Mathematica and as President of the International Mathematical Union. He is also the author of a number of influential books.

Lennart has received many awards in recognition of his work, including the Wolf Prize in Mathematics in 1992 and the Abel Prize in 2006. In addition to being a Foreign Member of the Royal Society, he is an elected member of the London Mathematical Society, the Norwegian Academy of Science and Letters and the American Mathematical Society.


  • Abel Prize

    For profound and seminal contributions to harmonic analysis and the theory of smooth dynamical systems.

  • Sylvester Medal

    For his deep and fundamental contributions to mathematics in the field of analysis and complex dynamics. His most spectacular achievement was the proof of the convergence almost everywhere of the Fourier Series of square integrable and continuous function

  • Wolf Prize

    In the field of mathematics for his fundamental contributions to Fourier analysis, complex analysis, quasi-conformal mappings and dynamical systems.
