Balanced Abelian group valued functions on directed graphs

Yonah Cherniavsky, Avraham Goldstein, Vadim E. Levit

We discuss functions from the edges and vertices of a directed graph to an Abelian group. Such functions, when the sum of their values along any cycle is zero, are called balanced…

Structure of the Group of Balanced Labelings on Graphs, its Subgroups and Quotient Groups

Yonah Cherniavsky, Avraham Goldstein, Vadim E. Levit

We discuss functions from edges and vertices of an undirected graph to an Abelian group. Such functions, when the sum of their values along any cycle is zero, are called balanced l…
