Abstract
Let R be a commutative ring and PG(R) is a graph whose vertices are all the elements of ring R and two vertices are adjacent if their product is zero. In this article, we study the energy of 1-Quasitotal and 2-Quasitotal Prime Graph of a Ring Zp and also find the energy of PG 1 (Zp ) and PG 2 (Zp ), p prime. A General SCILAB Software code for our calculation is also presented.
