The present paper is devoted to a general approach to the stability problem for integrable dynamical systems, based on the systematic use of methods from topological analysis, especially for the case of two degrees of freedom. To illustrate their method, the authors constructed a new tool called the bifurcation complex for two classical problems in the dynamics of a rigid body, namely the Goryachev-Chaplygin top and the Clebsch system (which is an integrable case of the motion of a rigid body in a fluid), as well as for the Gaffet system describing the dynamics of a gaseous ellipsoid filled with a monatomic ideal gas.
