Gaussian Vertex Prime Labeling of Some Graphs Obtained from Origami Models
Published in N. P. Shrimali, Nita H. Shah, Recent Advancements in Graph Theory, 2020
Gaussian integers are complex numbers of the form γ = x + iy where x and y are integers and i2 = −1. The set of Gaussian integers is usually denoted by Z[i]. A Gaussian integer γ is said to be an even Gaussian integer if γ is divisible by 1 + i and otherwise is called an odd Gaussian integer. The norm on Z[i] is defined as d(x + iy) = x2 + y2. One can easily see that the only units of Z[i] are ±1, ± i. The associates of Gaussian integer γ are unit multiples of γ. In Z[i], two Gaussian integers are relatively prime if their common divisors are the only units of Z[i]. A Gaussian integer γ is said to be a prime Gaussian integer if and only if ±1, ± i, ± γ, ± iγ are the only divisors of γ.

A Gaussian integer is a complex number: Z[i] = {a + bi : a, b ∈ ℤ}, where both a and b are integers. Gaussian integers, with ordinary addition and multiplication of complex numbers, form an integral domain. The norm of a Gaussian integer is a natural number, defined as |a + bi| = a2 + b2.
