Abstract

In this talk, I will discuss our recent results on the hydrodynamic limit problem for a kinetic flocking model of Cucker-Smale type. Using the Cucker-Smale model as an example, we develop systematically a GCI-based expansion method, and micro-macro decomposition on the dual space, to justify the limits to the macroscopic system, a non-Euler type hyperbolic system. We believe our method has widely application in the collective motions and active particle systems. This is a joint work with Prof. Ning JIANG and Prof. Yi-Long LUO.

      Cauchy two-matrix model, C-Toda lattice and CKP hierarchy I

      AbstractStarting from the symmetric reduction of Cauchy bi-orthogonal polynomials, we derive the Toda equation of CKP type (or the C-Toda lattice) as well as its Lax pair by introducing the time flow. Determinant solutions of the C-Toda lattice are expressed in terms of matrix integrals which can be extended to give matrix integral solutions of the CKP hierarchy. It is remarkable that the time-...
