| Abstract: | A coupled dynamos model considering two loss characteristics can be described as a threedimensional nonlinear autonomous system proposed recently by HAO et al, which exhibits very complicated dynamics. In this paper, invariant algebraic surfaces of this system are investigated from the view of integrability. Using the method of characteristic curves for solving linear partial differential equations, we obtain the parameter conditions when the system has invariant algebraic surfaces. |
