Title: Integrability in several random models

Abstract: Motivated by the relationship between field theory and classical integrable systems, there have been lots of studies in random matrices, orthogonal polynomials and integrable systems. In this talk, I will briefly review the relationship between random matrix models and KP hierarchies of A, B, C and D types. Then some discussions about non-intersecting Brownian motions and classical integrable systems will be made.
