Abstract: We prove that, in every closed Riemannian three-manifold $(M^3,\bar g)$, there exists a constant $C=C(M,\bar g)>0$ such that every closed smoothly embedded minimal surface $Σ\subset M$ satisfies $b_1(Σ;\mathbb{Z}_2)\le C\bigl(\operatorname{Ind}(Σ)+\operatorname{Area}(Σ)\bigr)$, establishing Song's additive genus-index-area conjecture. For closed connected orientable two-sided minimal immersions, we prove the universal inequality $γ(Σ)\le8\operatorname{Ind}(Σ)$ in positive Ricci curvature and the estimate $γ(Σ)\le C(M,\bar g)\operatorname{Ind}(Σ)$ in positive scalar curvature. In the latter case, we also bound both area and total curvature by $C(M,\bar g)(1+\operatorname{Ind}(Σ))$.
