| Résume | We introduce new spaces of martingales that behave like L_1 based Sobolev spaces on R^d. We prove a martingale analog of the Gagliardo--Nirenberg inequality (and more recent Van Schaftingen's theorem) and provide sharp estimates on the lower Hausdorff dimension of the terminal distributions of martingales in these spaces.
The talk is based on joint work with Rami Ayoush and Michal Wojciechowski. |
