Prime Labeling of Jahangir Graphs

Abstract: The paper investigates prime labeling of Jahangir graph Jn,m   for n ≥ 2, m ≥ 3 provided that nm is even. We discuss prime labeling of some graph operations viz. Fusion, Switching and Duplication to prove that the Fusion of two vertices v1 and vk where k is odd in a Jahangir graph Jn,m results to prime graph provided that the product nm is even and is relatively prime to k. The Fusion of two vertices vnm + 1 and vk for any k in Jn, m is prime. The switching of vk in the cycle Cnm of the Jahangir graph Jn,m  is… Show more

“…Beberapa kelas graf yang merupakan graf prima diantaranya graf gurita (Edward, Samuel, & Kalaivani, 2016), graf Lilly (Samuel & Kalaivani, 2018a), graf drum (Samuel & Kalaivani, 2018) dan graf Jahangir (Lakshmi et al, 2018). Graf prima juga dapat diperoleh dari hasil operasi antar graf-graf prima (Prajapati & Gajjar, 2014).…”
