Multiset and Mixed Metric Dimension for Starphene and Zigzag-Edge Coronoid

Let Γ=(V,E) be a simple connected graph. A vertex is said to recognize (resolve) two different elements b1 and b2 from V(Γ)∪E(Γ) if d(a,b1)≠d(a,b2}. subset of distinct ordered vertices UM⊆V(Γ) mixed metric generator for Γ each pair V∪E are recognized by some element UM. The with minimum number called basis Γ. Then, the cardinality this dimension Γ, denoted mdim(Γ). concept studying chemical structures using graph theory terminologies both appealing practical. It enables researchers more precisely easily examines various topologies networks. In paper, we consider well-known structures; starphene SPa,b,c six-sided hollow coronoid HCa,b,c respectively compute their multiset dimension.
