Abstract: In the paper, a description of the subgroups of uniformly bounded degree of the Cremona group of arbitrary rank is given. Such subgroups appear naturally in CR geometry as subgroups of holomorphic automorphisms of nondegenerate model surfaces.
Keywords: CR geometry, model surface, Cremona group
