Query: Abelian networks II. Halting on all inputs   Abelian networks are systems of communicating automata satisfying a local
commutativity condition. We show that a finite irreducible abelian network
halts on all inputs if and only if all eigenvalues of its production matrix lie
in the open unit disk.
