FACES OF MATHEMATICS

Professor Andrew Stuart

Warwick University

Andrew Stuart is a leading numerical analyst, and his work has been at the forefront of the development of computational analysis of evolving systems. He has investigated the relationships between dynamical systems and their computational models, and has contributed theoretical and practical advances in that area, as well as to the study of differential equations. His work is internationally renowned, and has been recognised by the award of numerous prizes.

"What I try to do is to use modern tools for understanding evolution problems to interpret algorithms, to understand the senses in which they are good or bad, to try to differentiate between existing algorithms, and to try to get insight into how you might construct new algorithms that will have some desirable property.

"I like the opportunity to go and learn something new, and then use it to try and understand some phenomena that I think are of interest. There is always that aspect, of choosing something that I find mathematically stimulating. I try to choose problems that are coming from reality, that have structures that come from applications that people are interested in.

"I might have some material that I am broadly interested in, and I've seen some resonance between that piece of mathematics and some application, and I'll then start to try to look in a little bit more detail at how those things fit together, and to see whether my intuition was right, that this piece of mathematics will be useful to help understand that kind of problem.

"I like the fact that mathematics is going on in my mind all the time, but sometimes I don't. Does that make sense?"
