Workshop on Fractional Processes in Finance at l'X

The Applied Mathematics Center of École Polytechnique organized an international workshop on Fractional Processes in Finance on June 11th on the campus of l'X.

This event took place in amphitheater Lagarrigue on the campus of l’X from 9am to 5pm and was organized by Josselin Garnier, Professor of applied mathematics, Mathieu Rosenbaum, Researcher at the applied mathematics Center at l’X and Knut Sølna, Professor of Mathematics currently on sabbatical at École Polytechnique and the Cournot Centre in Paris. This event was supported by École Polytechnique, University Paris-Saclay and the Cournot Centre, an independent French-based Research Institute.
