Thanks for pointing at this, if any of you post it as an answer, I would accept it for sure.

@DavidMitra: as each functional on $l_\infty$ is also a functional on $c_0$, the set of functionals on $c_0$ includes the set of functionals on $l_\infty$.

@DavidMitra: from 2. follows, that each continuous functional on $l_\infty$ can be narrowed to be a continuous functional on $c_0$ - and it's the same as the third statement.

comment Proving that $\cos(n^a t)$ doesn't converge to $1$
@user37238: I mean pointwise convergence, for all $t$. So, if it doesn't converge for one $t$ - then what I need is proven.

Oh, I understood you, that order is on pairs of vertices. Thanks also for giving such notion on BFS.

comment Breadth-first search tree
Is total order really necessary for BFS? Can't we just take a random vertex from list of adjacent ones on each step?
