 Sep24 awarded Autobiographer Jul2 awarded Curious Mar20 accepted What's wrong in this reasoning of $l_\infty$ separability? Mar20 comment What's wrong in this reasoning of $l_\infty$ separability? Thanks for pointing at this, if any of you post it as an answer, I would accept it for sure. Mar20 comment What's wrong in this reasoning of $l_\infty$ separability? @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 $l_\infty$. Mar20 comment What's wrong in this reasoning of $l_\infty$ separability? @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.

So, if it doesn't converge for one $t$ - then what I need is proven.

Apr2 comment Breadth-first search tree Oh, I understood you, that order is on pairs of vertices. Thanks also for giving such notion on BFS.
