Convexity of mean convex asymptotically conical self-expanders to the mean curvature flow

In this paper, we investigate the convexity of mean convex asymptotically conical self-expanders to the mean curvature flow in ${\mathbb{R}}^{n+1}$. Specifically, for $n\ge 3$, we show that any $n$-dimensional complete mean convex self-expander asymptotic to mean convex and weakly convex cones must be strictly convex.
