Abstract :
The present article continues the investigation of visible ideal bases in constructions defined usingdirected graphs. Our main theorem establishes that, for every balanced digraph D and eachidempotent semiring R with 1, the incidence semiring ID(R) of the digraph D has a convenientvisible ideal basis BD(R). It also shows that the elements of BD(R) can always be used to generatetwo-sided ideals with the largest possible weight among the weights of all two-sided ideals in theincidence semiring.
