Abstract: Indecomposible semifinite harmonic functions on the direct product of graded graphs are classified. As a particular case, the full list of indecomposible traces for the infinite inverse symmetric semigroup is obtained.
Key words and phrases: semifinite traces, AF-algebras, harmonic functions, branching graphs, infinite inverse symmetric semigroup.
