After 18 months of decline, the price of hydrocarbons seems to have stabilized at the end of 2015. How can we interpret this recent development and the preceding periods?
The conference will present empirical groundwork on the new price regime that is taking shape. What do the data tell us? How have spot prices, relative prices evolved?
The conference will focus on macroeconomic and geopolitical theoretical developments: Which elements determine market prices? What are the expectations in global growth? How have representations changed, in particular on financial markets?

The work of Kiyosi Itô and the Japanese school of stochastic processes that he founded is exceptional both in its beauty as pure mathematics and in the insights it has provided in biology, chemistry, quantum physics, electrical engineering, and finance. As the International Mathematical Union attested in awarding Itô its first Carl Friedrich Gauss prize in 2006, his work ranks as part of the world’s cultural heritage.
From its outset, however, Itô’s work has stood in a special relationship to French mathematicians. The first citation in Itô’s published work, in fact, the first sentence of his first article, was to Paul Lévy’s, Théorie de l’addition des variables aléatoires. As Itô later wrote, he learned stochastic processes from this book. His goal was to make fully mathematical the beautiful structure the book depicted, and he succeeded. It is often said that other French mathematicians understood Lévy only after Itô had explained his contribution. Thirty years later, in the 1970s, Itô was still interacting with French mathematicians, embracing and further developing PaulAndré Meyer’s semimartingalebased version of Itô’s theory of stochastic integration. Today, French mathematicians remain among those most keen to develop the applications of Itô’s calculus in physics and finance.
This conference examines Itô’s legacy from the perspective of this relationship. Is the theory of stochastic processes now truly a theory of sample paths as Lévy had envisioned? What has made Lévy processes and Itô’s understanding of stochastic integration so fruitful for applications in physics and finance? Where is Itô’s legacy taking us today?

 This conference brings together renowned probabilists from diverse scientific fields – probability theory, biology, geophysics, linguistics. By comparing definitions and methods, they assess the advance of probability in their respective disciplines and throughout the sciences as a whole. How do these disciplines intersect or diverge? Is there a common research agenda? What are the next steps in the development of probability?

• Noureddine el Karoui (UC, Berkeley), The Relationship between Probability and Statistics
• Alice Guionnet (M.I.T.), Progress in Random Matrices
• Johan Paulsson (HMS), Defining a Stochastic Research Agenda in Systems Biology
Part II 1:30 – 3:30 pm: The Probability Approach
