Integrable systems consist in a special class of overdetermined sets of partial differential (or difference) equations. They appear in several contexts in slightly different guises, including Random Matrix Theory, Moduli Spaces of Riemann surfaces and connections, Stochastic Processes and Inverse problems. A common thread to all these instances is the possibility of reformulation in terms of a particular boundary value problem for matrix-valued analytic functions, or what is now commonly referred to as a Riemann-Hilbert problem (RHP). The proposed research seeks to both advance the general understanding of RHPs as well as their application to several outstanding problems.

可积系统包含一类特殊的偏微分（或差分）方程超定集。它们出现在几个上下文中略有不同的伪装，包括随机矩阵理论，黎曼曲面和连接的模空间，随机过程和逆问题。所有这些例子的一个共同点是，对于矩阵值解析函数的特定边值问题，或者现在通常被称为黎曼-希尔伯特问题（RHP），可以重新表述。拟议中的研究旨在促进对RHP的普遍理解以及它们在几个突出问题中的应用。
