Abstract
Area preserving diffeomorphisms of the 2-disk which are identity near the b oundary form a group D-2 which can be equipped, using the L-2-norm on its L ie algebra, with a right invariant metric. With this metric the diameter of D-2 is infinite. In this paper we show that D-2 contains quasi-isometric e mbeddings of any finitely generated free group and any finitely generated a belian free group.
