摘要:AbstractA Radio Mean labeling of a connected graphGis a one to one mapffrom the vertex setV(G)to the set of natural numbersNsuch that for two distinct verticesuandvofG,d(u,v)+⌈f(u)+f(v)2⌉≥1+diam(G). The radio mean number off,rmn(f), is the maximum number assigned to any vertex ofG.The radio mean number ofG,rmn(G)is the minimum value ofrmn(f)taken over all radio mean labelingsfofG. In this paper we find the radio mean number of graphs with diameter three, lotus inside a circle, Helms and Sunflower graphs.
