| Povzetek: | A $(1,2)$-dominating set in a graph ▫$G$▫ is a set $S$ such that every vertex outside $S$ has at least one neighbor in $S$, and each vertex in $S$ has at least two neighbors in $S$. The $(1,2)$-domination number, $\gamma_{1, 2}(G)$, is the minimum size of such a set, while $c_{\rm ind}(G)$ is the cardinality of the largest vertex set in that induces one or more cycles. In this paper, we initiate the study of a relationship between these two concepts and discuss how establishing such a connection can contribute to solving a conjecture on the lower bound of $c_{\rm ind}(G)$ for cubic graphs. We also establish an upper bound on $c_{\rm ind}(G)$ for cubic graphs and characterize graphs that achieve this bound. |
