Query: Monopole star products are non-alternative   Non-associative algebras appear in some quantum-mechanical systems, for
instance if a charged particle in a distribution of magnetic monopoles is
considered. Using methods of deformation quantization it is shown here, that
algebras for such systems cannot be alternative, i.e. their associator cannot
be completely anti-symmetric.
