Let $T[\Sigma_0]$ denote the level-set flow associated with the translator $\Sigma_0$, and suppose that $T[\Sigma_0]$ fattens. A complete translator is called unstable or mathcal{I…

Let $F_t(M)$ denote the level set flow starting from a closed embedded surface $M$. Its singularities are called cylindrical or spherical when their tangent flows have the correspo…
