“…and Olshanetsky[11] developed a general framework in which the Schlesinger system and Korotkin and Samtleben's isomonodromic system are placed, along with generalizations to higher genus Riemann surfaces, in a unified way. Some more examples of matrix systems with different structures are also known[12,13,14,15]. Compared with Okamoto and Iwasaki's formulation, these "elliptic analogues of the Schlesinger system" are obtained on an entirely different ground, such as conformal field theories, vector bundles on a torus, KZ equations, and (classical or quantum) integrable systems.…”
