Spherical Geometries and Multigroups

Canadian Journal of Mathematics, 1950
1. Introduction. The notion spherical geometry is suggested by the familiar geometry of the Euclidean 2-sphere in which the role of path is played by “arc of great circle”. The first postulational treatment of the subject seems to be that of Halsted [10] for the two-dimensional case.

Anyon exciton: Spherical geometry

Low Temperature Physics, 1997
An anyon exciton formed by a valence hole and three quasielectrons of the Laughlin incompressible liquid of the fractional quantum Hall effect with the filling factor ν=1/3 is investigated numerically in a spherical geometry. The quasielectrons ar treated as Bose particles with hard cores and the Coulomb interaction.

Modons in spherical geometry

Geophysical & Astrophysical Fluid Dynamics, 1984
Abstract The analytical form of equivalent modons in spherical geometry is derived along with the dispersion relationship relating the modon frequency, spatial extent and interior wavenumber. The structure of equivalent modons in spherical geometry is more asymmetric as the geographic pole is approached, thus giving improved kinematic agreement with ...

Convection in Spherical Geometries

1985
Under well-defined conditions systems with many degrees of freedom like lasers, plasmas and fluids show irregular behaviour in their time evolution. These chaotic motions are usually produced by few degrees of freedom only and the basic question arises how to determine these relevant variables and to describe their dynamics.
