Jul 27 comment How to prove connectivity $\leq$ minimum degree? Thanks. Seem we have different definition of connectivity, but yours seems better for this question.

May 6 comment Relation about Gateaux differentiable and differentiable differentiable is what we meet in undergraduate calculus course (see, e.g., Def. 9.11 in P212 of baby Rudin). Gateaux differentiable (at x) is defined as follows: (1)the directional derivative $f'(x;v)$ exists for all $v\in\mathbb{R}^n$, (2)there exists (unique) $f_G'(x)\in\mathbb{R}^*$ such that $f'(x;v)=$ for all $v\in\mathbb{R}^n$, where $\mathbb{R}^*$ means the dual space of $\mathbb{R}^n$.
