Minimal hypersurfaces of finite $δ$-index in $\mathbb R^4$ and $\mathbb R^5$

Let $X:M^n\to\mathbb R^{n+1}$ be a complete, connected, two-sided minimal immersion without boundary, where $n=3,4$. We prove that finite $δ$-index, finite Morse index, and finite total curvature are equivalent for $δ>((n-1)/n)^2$, without assumptions on properness, volume growth, or topology. The m
