Professors in Israel, the US, France and Germany are to receive prestigious Wolf Prizes this year for achievements in mathematics and physics, the Wolf Foundation announced on Tuesday. The foundation pronounced mathematics prizewinner Professor Harry Furstenberg of the Hebrew University of Jerusalem "one of the great masters of probability theory, ergodic theory and topological dynamics." "He is a builder of bridges among the various mathematical disciplines," said a former student, Professor Alex Lubotzky of the Hebrew University. "He greatly influenced a wide array of mathematical subjects and built new fields of mathematics that connected them." The $100,000 (â‚¬77,000) prize in each field is to be presented at a ceremony in Jerusalem on May 13. The Israel-based foundation was established by Ricardo Wolf, a German-born inventor, diplomat and philanthropist.
