Let \(G=(V,E)\) be a graph. A subset \(D\subseteq V\) is a total dominating set of \(G\) if for every vertex \(y\in V\) there is a vertex \(x\in D\) with \(xy\in E\). A subset \(D\subseteq V\) is a strong dominating set of \(G\) if for every vertex \

In this paper we show that at most $2 \gcd(m,n)$ points can be placed with no three in a line on an $m\times n$ discrete torus. In the situation when $\gcd(m,n)$ is a prime, we completely solve the problem.

In the forging of steel anges with neck, where the forging temperature is around 1150 °C, it places extremely high demands on the dies. Abrasive wear, thermal fatigue, adhesion, etc. are very important parameters affecting the durability of forging

In this paper we prove that @c"r"2(C"[email protected]?C"5)>=2n. This, together with the result of [email protected]?pien and Zwierzchowski (2014), gives @c"r"2(C"[email protected]?C"5)=2n. Since for n=5k we have @c(C"[email protected]?C"5)=n (see Kl

The concept of 2-rainbow domination of a graph $$G$$G coincides with the ordinary domination of the prism $$G\Box K_{2}$$G?K2 (see Bresar et al., Taiwan J Math 12:213---225, 2008). Hence $$\gamma _{r2}(C_{m}\Box C_{n})\ge \frac{mn}{3}$$?r2(Cm?Cn)?mn3

A function $$f:V(G)\rightarrow \mathcal P (\{1,\ldots ,k\})$$ is called a $$k$$ -rainbow dominating function of $$G$$ (for short $$kRDF$$ of $$G)$$ if $$ \bigcup \nolimits _{u\in N(v)}f(u)=\{1,\ldots ,k\},$$ for each vertex $$ v\in V(G)$$ with $$f(v)
