Abstract:
We describe subgroups of elements of uniformly bounded degrees in Cremona groups of arbitrary rank. These subgroups appear naturally in $\mathrm{CR}$-geometry as holomorphic automorphism groups of nondegenerate homogeneous model surfaces.
Keywords:$\mathrm{CR}$-geometry, model surface, Cremona group.
