Miklós Laczkovich (born 21 February 1948) is a Hungarian mathematician mainly noted for his work on real analysis and geometric measure theory. His most famous result is the solution of Tarski's circle-squaring problem in 1989.[1]


Laczkovich received his degree in mathematics in 1971 at Eötvös Loránd University, where he has been teaching ever since, currently leading the Department of Analysis. He was also a professor at University College London, where he is now a professor emeritus.[2] He is corresponding member (1993), member (1998) of the Hungarian Academy of Sciences. He has held several guest professor positions in the UK, Canada, Italy and the United States.

Also being a prolific author, he published over 100 papers and two books, one of which, the Conjecture and Proof, was an international success. One of his results is the solution of the Kemperman problem: if f is a real function which satisfies 2f(x) ≤ f(x + h) + f(x + 2h) for every h > 0, then f is monotonically increasing.



Professor Laczkovich enjoys and performs classical music; he has been active in various choirs in the past decades.
