Abstract

Let G = (V, E) be a simple graph. A function f : E → {+1,−1} is called a signed cycle domination function (SCDF) of G if ƩeE(C)f(e) ≥ 1 for every induced cycle C of G. The signed cycle domination number of G is defined as γsc(G) = min{ƩeEf(e)| f is an SCDF of G}. This paper will characterize all maximal planar graphs G with order n ≥ 6 and γsc(G) = n.
