Reinout Quispel (La Trobe University)

Abstract:
This talk will be in two parts:
The first part will be introductory, and will address the question: Given an ordinary differential equation (ODE) with certain physical/geometric properties (for example a preserved measure, first and/or second integrals), how can one preserve these properties under discretization?
The second part of the talk will cover some more recent work, and address the question: How can one deduce hard to find properties of an ODE from its discretization?
