On 2-Rainbow Domination of Generalized Petersen Graphs P(ck,k)Brezovnik, Simon (Avtor) Rupnik Poklukar, Darja (Avtor) Žerovnik, Janez (Avtor) rainbow domination2-rainbow domination numbergeneralized Petersen graphsWe obtain new results on the 2-rainbow domination number of generalized Petersen graphs $P(ck, k)$. Exact values are established for all infinite families where the general lower bound $\frac{4}{5}$$ck$ is attained. In all other cases lower and upper bounds with small gaps are given.20232025-04-24 09:59:22Članek v reviji168782UDK: 519.17ISSN pri članku: 2227-7390DOI: 10.3390/math11102271COBISS_ID: 152994051sl
