Graph energy and topological descriptors of zero divisor graph associated with commutative ring.

Let R be a commutative ring with all non-zero zero divisors Z ∗ (R) of R . Then Γ (R) is said to be a zero divisor graph if and only if a · b = 0 where a , b ∈ V (Γ (R)) = Z ∗ (R) and (a , b) ∈ E (Γ (R)) . Graph energy E (Γ (R)) is defined as the sum of the absolute eigenvalues of the adjacency matrix of Γ (R) , then E (Γ (R)) = ∑ i = 1 n | λ i | . A topological index is a numeric quantity associated with a chemical structure that attempts to link the chemical structure to various physicochemical properties, chemical reactivity, or biological activity. This paper discusses the graph energy and various topological indices of zero divisor graph associated with the commutative ring. [ABSTRACT FROM AUTHOR]
