Zdeněk Dvořák


Zdeněk Dvořák (born April 26, 1981) is a Czech mathematician specializing in graph theory.

Dvořák was born in Nové Město na Moravě. He competed on the Czech national team in the 1999 International Mathematical Olympiad, and in the same year in the International Olympiad in Informatics, where he won a gold medal. He earned his Ph.D. in 2007 from Charles University in Prague, under the supervision of Jaroslav Nešetřil. He remained as a research fellow at Charles University until 2010, and then did postdoctoral studies at the Georgia Institute of Technology and Simon Fraser University. He then returned to the Computer Science Institute (IUUK) of Charles University, obtained his habilitation in 2012, and is now an associate professor there.

He was one of three winners of the 2015 European Prize in Combinatorics, "for his fundamental contributions to graph theory, in particular for his work on structural aspects of graph theory, including solutions to Havel’s 1969 problem and the Heckman–Thomas 14/5 problem on fractional colourings of cubic triangle-free graphs. This refers to two different results of Dvořák:
