Record completeness
Claims
We prove that Γ_P(R) ≅ K_{|P|-1} ∨ K-bar_{|R|-|P|}, and a monomial x^α y^β belongs to the minimal generators of I(Γ_P(R))^n if and only if |α| + |β| = 2n, |β| ≤ n, and 0 ≤ α_i ≤ n for all i.
R is a finite commutative ring with identity and P is a proper prime ideal; this finiteness and the prime property are used to obtain the explicit isomorphism and the counting formulas.
Prime ideal graphs are complete split graphs whose edge ideal powers have explicit minimal monomial generators satisfying exponent conditions, are polymatroidal with linear resolutions, and have computable analytic spread.
