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?

Biography: Reinout Quispel was an undergraduate at the University of Utrecht (the 
Netherlands) for nine years, before obtaining a PhD on the discretization of soliton 
theory from Leiden University in 1983. He moved to Australia for a three-year position 
in 1986 and is still there 35 years later. His main areas of expertise are in 
integrable systems and in the geometric numerical integration of differential equations.
He was awarded the Onsager Professorship and Medal by the Norwegian University of 
Science and Technology (NTNU) in 2013.
