Query: Integrable Yang-Mills-Higgs Equations in 3-Dimensional De Sitter
  Space-Time   This paper describes an integrable Yang-Mills-Higgs system on
(2+1)-dimensional de Sitter space-time. It is the curved-space-time analogue of
the Bogomolnyi equations for monopoles on R^3. A number of solutions, of
various types, are constructed.
