Taking inspiration from the movements of planets and the behaviour of matter, the Russian student Olga Romaskevich is exploring pure mathematics: geometry and dynamics. She works in particular on the statistical properties of dynamical systems, following the theory known as “ergodic”, where measurements taken on a trajectory chosen randomly provide information on the general state of the system. “If a boat measures the temperature in the sea by following a random trajectory, the average of the results gathered will give the average temperature of the whole sea”, is how she simplifies this idea. She hopes that a better understanding of these mathematical models will be able to facilitate an understanding of real physical phenomena.
Olga Romaskevich, whose doctorate is under the joint supervision of the Pure and Applied Mathematics Unit at the Ecole Normale Supérieure in Lyon and the Moscow School for Higher Studies in Economic Science, is also inspired by the sharing of knowledge. In a collaboration between the Ecole Normale Supérieure in Lyon and the Musées des Confluences (Museum of Convergences), she has created a virtual exhibition on celestial mechanics. “I try to do everything possible to promote the image of mathematics in society.”
