Emergent properties are an inexhaustible well of interactions between scientific disciplines. Organized without using a centralized command system. These systems are very interesting to physicists and mathemati- cians, since they become more and more This idea featured in the work of the first economists like Bernard Mandeville, David Hume, and of course Adam Smith with his famous "invisible hand". How would you define emergent properties?Īn emergent property is a system pro- perty that is not a property of any of the system's components, but of the system as a whole. For several years, I have been conducting a general explo- ration of emergent properties in various applications. I have, for instance, done a lot of work with biologists on model- ling the emergence of a population of multicellular organisms from single- celled organisms. Mathematics can of course be a great help in other disciplines. For instance, I worked on Beckmann-type models for urban economics that use mathemati- cal theories of optimal transportation to help understand how people choose their spatial allocations.Įconomists, and this is especially true at TSE, are advanced mathematicians, and we have a natural shared understanding of the problems we face, which makes it
I took part in seminars, particularly on theo- retical economics, and held discussions with many colleagues, which enabled me to use my own expertise to respond to various economic questions and develop new research avenues at the crossroads between our disciplines. When I arrived in 2008, I chose Toulouse above all to join an excellent research group working on applied mathematics and for the opportunity to explore inte- ractions with Toulouse economists.
