Miklós Laczkovich (born 21 February 1948) is a
Hungarian mathematician mainly noted for his work on
real analysis
In mathematics, the branch of real analysis studies the behavior of real numbers, sequences and series of real numbers, and real functions. Some particular properties of real-valued sequences and functions that real analysis studies include co ...

measure theory
In mathematics, the concept of a measure is a generalization and formalization of geometrical measures (length, area, volume) and other common notions, such as magnitude (mathematics), magnitude, mass, and probability of events. These seemingl ...

He became corresponding member (1993), then 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, ''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 2''f''(''x'') ≤ f(''x'' + ''h'') + ''f''(''x'' + 2''h'') for every ''h'' > 0, then ''f'' is monotonically increasing.
