Miklós Laczkovich
Encyclopedia
Miklós Laczkovich 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.
. 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.
; he has been active in various choirs in the past decades.
Real analysis
Real analysis, is a branch of mathematical analysis dealing with the set of real numbers and functions of a real variable. In particular, it deals with the analytic properties of real functions and sequences, including convergence and limits of sequences of real numbers, the calculus of the real...

Tarski's circle-squaring problem
Tarski's circle-squaring problem is the challenge, posed by Alfred Tarski in 1925, to take a disc in the plane, cut it into finitely many pieces, and reassemble the pieces so as to get a square of equal area. This was proven to be possible by Miklós Laczkovich in 1990; the decomposition makes heavy...
