Abstract: We define and study classes of vector martingales obeying special restrictions imposed on martingale differences. We prove an analog of the Sobolev embedding theorem for such martingales and give the (exact) bound of the Hausdorff dimension of their limit measures.

Joint work with Rami Ayoush and DIma Stolyarov.
