Let 𝐺 = (𝑉,𝐸), 𝑉={1,2,...,𝑛}, be a simple connected graph of order𝑛, size 𝑚 with vertex degree sequence 𝑑1 ≥ 𝑑2 ≥ ... ≥ 𝑑𝑛 > 0, 𝑑𝑖 = 𝑑(𝜐𝑖). The geometric–arithmetic topological index ...

Vertices arrive sequentially in space and are joined to existing vertices at random according to a preferential rule combining degree and spatial proximity. We investigate phase transitions in the ...

Each term in this sequence is doubling (multiplying by 2) to create the next term. Number sequences are sets of numbers that follow a pattern or a rule. If the rule is to multiply or divide by a ...
