János Körner is a Hungarian mathematician who works oninformation theory andcombinatorics.[1]
Körner studied Mathematics at theEötvös Loránd University in Budapest with a degree in 1970[2] and was then at theAlfréd Rényi Institute of Mathematics of theHungarian Academy of Sciences until 1992. From 1981 to 1983 he was at theBell Laboratories and in 1987–88 atTélécom Paris (ENST) in Paris.[2] He has been a professor at theSapienza University of Rome since 1993.[1]
Over his career, he frequently collaborated with fellow information theorists such asRudolf Ahlswede,Katalin Marton, andImre Csiszár. Together with Rudolf Ahlswede and Peter Gács he proved the blowing-up lemma.[3] Besides information theory, he also works onextremal graph theory.
In 2014 he received theClaude E. Shannon Award.[2] He served as Associated editor of theIEEE Transactions on Information Theory on multiple occasions. He is a member of the Hungarian Academy of Sciences.[1]
