Missing Numbers in -Graceful Graphs
The generalization of graceful labeling is termed as -graceful labeling. In this paper it has been shown that , is -graceful for any (set of natural numbers) and some results related to missing numbers for -graceful labeling of cycle , comb , hairy cycle and wheel graph have been discussed.
متن کاملGraceful Dialects
Programming languages are enormously diverse, both in their essential concepts and in their accidental aspects. This creates a problem when teaching programming. To let students experience the diversity of essential concepts, the students must also be exposed to an overwhelming variety of accidental and irrelevant detail: the accidental differences between the languages are likely to obscure th...
متن کاملGraceful and odd graceful labeling of some graphs
In this paper, we prove that the square graph of bistar Bn,n, the splitting graph of Bn,n and the splitting graph of star K1,n are graceful graphs. We also prove that the splitting graph and the shadow graph of bistar Bn,n admit odd graceful labeling.
متن کاملImproper Graceful and Odd-graceful Labellings of Graph Theory
Abstract In this paper we define some new labellings for trees, called the in-improper and out-improper odd-graceful labellings such that some trees labelled with the new labellings can induce graceful graphs having at least a cycle. We, next, apply the new labellings to construct large scale of graphs having improper graceful/odd-graceful labellings or having graceful/odd-graceful labellings.
