In the past decade, a variety of different mathematical problems have found a unifying element in the fact that they can be formulated, in some sense, as a so-called Riemann-Hilbert problem (RHP), a classical problem in complex analysis. The possibility of interpreting as a RHP many different mathematical questions, especially arising in the modelling of large or random systems, has lately received a lot of attention from the mathematical community, and RH formulations can be found in the context of random matrix theory, statistical physics, and fluid mechanics, for example. The objective of this meeting is to bring together people working in the areas of Riemann-Hilbert problems and their applications in different branches of mathematics and mathematical physics, such as random matrix theory, operator theory, and asymptotic analysis. The main aim is to discuss the current state of the field and, most importantly, to explore further plans for the future.
