We consider groups of orientation-preserving real analytic diffeo-morphisms of the circle which have a finite image under the rotation number function. We show that if such a group is nondiscrete with respect to the C 1-topology then it has a finite orbit. As a corollary, we show that if such a group has no finite orbit then each of its subgroups contains(More)
BACKGROUND Traditionally, we have been puncturing the internal jugular vein (IJV) with the head rotated. However, in adults it has been suggested that rotation of the head increases the magnitude of an overlapping of the IJV to the carotid artery (CA). Therefore, in infants and children, we have examined anatomic relationship between the IJV and the CA(More)
