论文摘要
带顶点套装$ v（d）$在Digraph $ d $上的意大利统治功能定义为函数$ f：v（d）\ rightarrow \ {0，1，2，2 \} $，使每个顶点$ v \ in v（d）$ f（v）= 0 $ f（v）= 0 $至少有两个$ 1 $ $ $ $ $ $ $或一个$ f。 = 2 $。在本文中，我们确定了某些定向循环产物的意大利统治数的确切值。
An Italian dominating function on a digraph $D$ with vertex set $V(D)$ is defined as a function $f : V(D) \rightarrow \{0, 1, 2\}$ such that every vertex $v \in V(D)$ with $f(v) = 0$ has at least two in-neighbors assigned $1$ under $f$ or one in-neighbor $w$ with $f(w) = 2$. In this paper, we determine the exact values of the Italian domination numbers of some products of directed cycles.
