摘要：

The symmetry, energy, dipole and quadrupole moments of the ground states in 'Thomson's problem' of point Coulomb charges on a sphere are found and analized for the number of charges N = 2-100. The equilibrium configurations are considered as closed quasi-2D triangular lattices with topological defects (disclinations of various charge). An appropriate classification of the structures is proposed. The approach is compared with the description of the configurations in terms of 'ring structures on sphere'. The problem has a number of physical and chemical realizations. (C) 1999 Elsevier Science B.V. All rights reserved.
