Gyrogroups and Gyrovector Spaces and Hyperbolic Geometry
We show that the algebra of the group SL(2; C) naturally leads to the notion of gyrogroups and gyrovector spaces for dealing with the Lorentz group and its underlying hyperbolic geometry. The superiority of the use of the gyrogroup formalism over the use of theSL(2; C) formalism for dealing with the Lorentz group in some cases is indicated by (i) the validity of gyrogroups and gyrovector spaces...
متن کاملMöbius syndrome.
We describe a case of Möbius syndrome in a 3-month-old infant. Striking imaging findings of pontine hypoplasia in the region of the 6th and the 7th nerve complexes were noted. In addition, absence of the middle cerebellar peduncles was noted, a finding that, to our knowledge, has never been reported before in the literature. Clinical presentations, other radiologic findings, and a possible path...

متن کاملMöbius Photogrammetry
Motivated by results on the mobility of mechanical devices called pentapods, this paper deals with a mathematically freestanding problem, which we call Möbius Photogrammetry. Unlike traditional photogrammetry, which tries to recover a set of points in three–dimensional space from a finite set of central projection, we consider the problem of reconstructing a vector of points in R3 starting from...
متن کاملGenetics of Möbius syndrome.
A study of the sibs and parents of 15 children diagnosed as having the Möbius syndrome suggests that the inclusion of primary skeletal defects as obligatory in the diagnosis of the syndrome helps to exclude the high risk monogenic disorders of muscle and anterior horn cell, which present with a Möbius-like facies in infancy.
