Letbe a graph. A functionis said to be a balanced cycle dominating function (BCDF) ofifholds for any induced cycleofThe balanced cycle domination number ofis defined as γbc′(G)=max {∑e∈E(G)f(e)|f is a BCDF of G}. A graphis said to be a signed cycle balanced graph (SCB-graph) if there exists a functionsuch thatholds for any induced cycleofandis said to be a signed cycle balanced dominating function (SCBDF) ofThe signed cycle balanced domination number ofis defined as γscb′(G)=max{∑e∈E(G)f(e)| f is an SCBDF of G}. In this paper, we present upper bounds for balanced cycle domination number and signed cycle balanced domination number. The exact values of this parameter are determined for a few classes of graphs.
