Asymptotic stability of robust heteroclinic networks

Given a heteroclinic network, there is an associated graph such that the vertices of the graph correspond to the equilibria of the network and an edge corresponds to a connection between equilibria. Classification of ac-networks is carried out by describing all possible types of asso- ciated graphs.

We prove sufficient conditions for asymptotic stability of certain robust heteroclinic networks. The proof is given as a series of theorems and lemmas that are applicable to the ac-networks and to more general types of networks. Finally, we apply these results to derive conditions for asymptotic stability of several heteroclinic networks.
