Title of Presentation
“Mathematics of Planet Earth”
Earth is a complex planet with an atmosphere, oceans and climates. The human species shares the planet with millions of living species, some of them invasive, and others in danger of disappearing. But what is the link with mathematics? Can mathematics help to understand and manage the planet? You will be surprised to see the variety of scientific questions to the answer of which mathematics can contribute. With mathematical tools, we can discover the history of the Earth, explore its interior, study its climates and find strategies for managing its ecosystems. Mathematics also plays a role in understanding the dangers faced by our planet and its inhabitants: epidemic diseases, global warming, sea level rise and growth of population.

 A brief Biography

Christiane Rousseau studied at University of Montreal where she got her PhD in 1977. After postdoctoral studies at McGill University, she came back to University of Montreal where she became professor. She chaired her department in 199397 and she has been President of the Canadian Mathematical Society from 2002 to 2004. When she was Director of Centre de Recherches Mathématiques (CRM) in 200809, she initiated the international year “Mathematics of Planet Earth 2013”, under the patronage of UNESCO. In 20112014, she was Vicepresident of the International Mathematical Union and she is presently a member of the Executive Committee of the International Mathematical Union. For 201517, she is a member of the Scientific Committee of the International Basic Science Program at UNESCO. Her research area is dynamical systems. During her whole career, she led in parallel research activities and outreach activities: lectures in the schools, organization of mathematical camps, and articles in mathematical magazines. Her book “Mathematics and technology” with Yvan SaintAubin paved the way to the teaching of new modern applications of mathematics to technology to preservice high school teachers.
