The Eduard Čech Distinguished Visitor Programme has been established with the aim to significantly enhance the creative environment in the Institute by bring here highly distinguished mathematicians for prolonged periods. The visitors are expected to deliver a series of at least three lectures for the mathematical community and to essentially develop scientific collaboration with the mathematicians in the Institute.

Yoshihiro

Yoshihiro Shibata is a professor at Waseda University, Tokyo. He is a worldrenowned expert on the mathematical theory of fluid flow and the theory of initialboundary value problems for partial differential equations of parabolic and hyperbolic type. Together with his colleagues, he came up with several fundamental results, such as the resolvent estimates for the Oseen problem, the LpLq theory of the Stokes semigroup, the theory of Rboundedness for compressible fluids, and its extension to the timeperiod case. In the period 20092014, he was the principal investigator of the International Externship between the Japan Society for the Promotion of Science and the DFG represented by Waseda University and TU Darmstadt, respectively. In the years 20142022, he was the leader of the Mathematics and Physic unit of Waseda University, and during 20102015 he served as the director of the Institute of Nonlinear Partial Differential Equations at Waseda University. In 2022, he delivered the Birkhauser Distinguished lecture. In May and June 2023, he will stay at the Institute of Mathematics as the Eduard Cech Distinguished Visitor. He will deliver a series of lectures on the problem of maximal regularity and free boundary for the NavierStokes equations, and he will pursue collaborative research mainly with colleagues from the Department of Evolution Differential Equations. Part of the programme of Prof Shibata's visit is the 19th Eduard Čech Lecture on 24th May 2023.

Ramamohan Paturi is a professor at the University of California, San Diego, USA. His research is focused on theoretical computer science, specifically communication complexity, the complexity of Boolean circuits, and, more recently, on the complexity of the problem of satisfiability of Boolean formulas (SAT). He is the coauthor of the fastest algorithm for kSAT, known as PPSZ. Together with Impagliazzo, they formulated the Exponential Time Hypothesis (ETH) hypothesis in 1999 and later its stronger version, the Strong Exponential Hypothesis (SETH). These hypotheses have proven to be very useful. They can determine the complexity of many problems for which we cannot prove anything without additional assumptions. As a part of his research programme at the Institute of Mathematics, he delivered the 18th Eduard Čech Lecture.

Antonín

Antonín Novotný is a professor of a special class at the Université du Sud Toulon. He is a leading specialist in the theory of compressible flows and an expert on singular limits for the complete system. Apart from this, he is interested in theoretical numerical analysis for compressible fluids. Antonín Novotný published on these topics three influential monographs. He received the medal of the Academy of Sciences in 2009, the Bolzano medal in 2018, and the silver medal of Charles University. From February to April 2021, he will stay at the Institute of Mathematics as the Eduard Čech Distinguished Visitor. He will deliver a lecture series entitled Dissipative and weak solutions to compressible NavierStokes equations: theory and numerical analysis and collaborate mainly with colleagues from the Department of Evolution Differential Equations.

Stevo Todorčević is one of the leading researchers in modern pure mathematics. He was an invited speaker at the ICM in Berlin in 1998, and a member of the program committee for the ICM in Madrid in 2006. He is a Fellow of the Royal Society of Canada, Fellow of the Fields Institute, and a Member of the Serbian Academy of Sciences and Arts. In 2013, he was awarded the Shoenfield Prize for his book. He gave the Alfred Tarski Lectures at the University of California in Berkeley in 2014, and he gave the Gödel Annual Lecture of the Association for Symbolic Logic in 2016. He was awarded CRMFieldsPIMS Prize in 2012, and he holds a Canada Research Chair professorship at the University of Toronto. His research in set theory, Ramsey theory, and functional analysis has strong connections with interests of Prague mathematicians.

Vojtěch Rödl belongs to the top world mathematicians in the field of combinatorics. He authored more than 300 articles. He became famous by his work in Ramsey theory but later obtained significant results in many other branches of combinatorics. Many of his results deal with Erdős's problems of which he has solved more than 20, including very difficult ones. In particular he and Peter Frankl proved the Erdős and Hanani conjecture. The method by which it was solved is referred to as Rödl nibble. His probably most famous result is a proof of the hypergraph regularity lemma, which he published with his students in a series of articles. This enables one to prove Szemerédi's theorem on arithmetic progressions in dense subsets of integers by purely combinatorial means as well as some other results of this kind.
