Dynamics of Lorenz maps Lorenz maps arise naturally in the study of a geometric model of Lorenz differential equations and have been investigated intensively. In this talk I will first review some of the classical results in this area. In particular, a piecewise continuous interval map whose derivative is constant everywhere, apart from at a finite number of points, is the simplest example of a Lorenz map and its dynamics is fairly well understood. I will discuss on how some features of a general Lorenz map can be studied via piecewise continuous interval maps.
Then I will present recent joint work with T. Samuel and A. Vince which addresses the question on when the symbolic dynamics of a given Lorenz map can be fully embedded in the symbolic dynamics of a piecewise continuous interval map. As an application of this embedding result, I will describe a new algorithm for calculating the topological entropy of a Lorenz map. If time permits, I will discuss some related open questions..
