József Balogh (mathematician)

from Wikipedia, the free encyclopedia

József Balogh is a Hungarian mathematician who studies graph theory and combinatorics .

Balogh grew up in Mórahalom and went to a special school for mathematics in Szeged. As a student, he won two silver medals at the International Mathematical Olympiads. He studied at the University of Ghent and the University of Szeged, where he received his diploma in mathematics in 1995 with Péter Hajnal (On the existence of MDS-cyclic codes). In 2001 he received his doctorate from the University of Memphis with Béla Bollobás (Graph properties and Bootstrap percolation). As a post-doctoral student he was at ATT Shannon Laboratories in Florham and in 2002 at the Institute for Advanced Study . In 2002 he became Zassenhaus Assistant Professor at Ohio State University and in 2005 Assistant Professor at the University of Illinois at Urbana-Champaign , where he became Associate Professor in 2010 and Professor in 2013.

From 2009 to 2011 he was also an Associate Professor at the University of California, Davis .

Balogh deals with extremal and probabilistic combinatorics (especially graph theory) and bootstrap percolation . The latter models the spread of an infection on a d-dimensional grid, with nodes being infected in each time step where at least r neighbors have already been infected. A randomly chosen initial structure is assumed and Bollobas, Balogh, Hugo Duminil-Copin and R. Morris proved an asymptotic (for large lattices) formula for the threshold probability that the whole lattice will be infected, depending on d and r. He had previously treated the three-dimensional case with r = 3 with Bollobas and Morris.

For 2018 he is invited speaker at the International Congress of Mathematicians in Rio de Janeiro . In 2013/14 he was a Simons Fellow and Marie Curie Fellow and received an NSF Career Grant. In 2016 he received the George Pólya Prize in combinatorics with Robert Morris and Samotij . Wojciech Samotij is one of his students .
