Plane-or-cylinder asymptotic conjecture for self-shrinkers

Let ΣR3\Sigma\subset\mathbb{R}^3 be a complete noncompact properly embedded self-shrinker with finite genus, and define its Gaussian surface area by

F[Σ]=(4π)1Σex2/4dH2.\mathbf{F}[\Sigma]=(4\pi)^{-1}\int_\Sigma\operatorname{e}^{-\lvert\mathbf{x}\rvert^2/4}\,d\mathcal{H}^2.

Assume that v0R3{0}\mathbf{v}_0\in\mathbb{R}^3\setminus\{\mathbf{0}\} satisfies F[Σλv0]1\mathbf{F}[\Sigma-\lambda\mathbf{v}_0]\geq 1 for all λ>0\lambda>0.

Plane-or-cylinder asymptotic conjecture. As λ\lambda\to\infty, Σλv0\Sigma-\lambda\mathbf{v}_0 converges locally smoothly to a plane or a self-shrinking cylinder of multiplicity one.

This is a reformulation intended to address the formation of singularities of self-shrinking mean-curvature flows at time 00. The source gives no evidence that the statement has been proved or disproved, so it remains open.
