Isomonodromic deformations and integrable systems (Q5944691)

Here, the author gives a possibly simple and graphical description of a relationship between the isomonodromic problem and integrable systems. One can construct a huge integral system which contains isomonodromic deformations as well as all known 2-dimensional integrable systems in the Zakharov-Shabat form as its restrictions. Besides, the author gives a proof of the isomonodromic property of the constructed deformations that is considerably easier than existent proofs.
