Abstract
Schwarzschild models of a Plummer sphere were constructed and compared with analytical results to test the robustness of Schwarzschild's method and its efficiency in probing the degeneracy of the solution space. The method was then used to construct and study the nonuniqueness of triaxial equilibria with central density cusps, for which no analytical solutions are known. The stability of some models was also tested via N-body simulations.
