报告摘要：We shall consider KP hierarchy together with its two-dimensional reductions. Polynomial, rational and logarithmic.Then we consider their dispershionless limits.Dispershionless limits of Lax representations and Isomonodromic deformations.Also we shall discuss hydrodynamic chains. Benney moment chain and Kupershmidt chains.Their relationships with three-dimensional quasilinear systems of first order.
