The list of plenary and invited speakers of next year's International Congress of Mathematicians has been announced. The event is organized in every four year for more than 120 years and being an invited speaker is the most prestigeous honour that a researcher can dream of apart from the international mathematical awards. Seven Hungarian speakers are invited to present a talk at the 2018 Rio de Janeiro meeting. Among them András Némethi, Balázs Szegedy, Gábor Tardos and Bálint Tóth are our colleagues at the Alfréd Rényi Insitute of Mathematics of the Hungarian Academy of Sciences (Bálint Tóth is also a professor at Bristol University), László Babai, József Balogh, and András Máthé work at the University of Chicago, University of Illinois Urbana-Champaign, Warwick University, respectively. Member of HAS László Babai has been invited for the third time thanks to his breakthrough result on the graph-isomorphism problem. Balázs Szegedy and Gábor Tardos are former awardees of the Momentum program of the Hungarian Academy of Scineces, while András Némethi received the Széchenyi Prize this year. Combinatorics has always been a 'Hungarian branch' of mathematics, it is therefore no surprise that four of the seven speakers (Babai, Balogh, Szegedy, and Tardos) are invited to this section. Máthé, Némethi, and Tóth will present their talks in the analysis, algebraic geometry, and probability theory sections.For comparison, it is worth noting that from the Eastern European region two researchers from Poland and one researcher from the Ukraine and Latvia each received an invitation to the meeting.
