comment Pursuers (a game)
@mvw The runner chooses arbitrary starting positions for both himself and for the pursuers.

comment Pursuers (a game)
@mvw The trajectory of the runner is any integral of an integrable vector function whose absolute value at every point is not above $v$. Likewise for pursuers (but with $u$ instead of $v$). If the runner's trajectory intersects one of a pursuer, the runner lose.

comment Pursuers (a game)
I don't know what is "round based". I ask whether initial positions, for which the runner may run infinitely, exist. In other words, initial positions can be taken arbitrarily. Initial velocity vectors are allowed to be arbitrary (as much that they are less $v$ for the runners and $u$ for the pursuers). Positions follow a differential equation for some continuous speed functions, that is are updated continuously.

comment A totally bounded uniformity and certain filters
@J.-E.Pin I think it is correct. However I asked this question almost a two years ago and may not remember the context of the issue.

comment Circle is similar to a polygon with infinite number of sides
@Kaster And I prefer it to be considered not as a limit, but as a "real" polygon with infinite number of sides. For example in complex number theory the infinity is not just a limit of finite values, but a quite particular point of Riemann sphere.

@Kaster I know that it is a limit. But what is the topology and what is the filter on which the limit is taken?

comment Name of the class of maps between posets such that $f(x)\le f(y)\implies x\le y$
Oh, if the implication holds also in the reverse direction, it is an order embedding. This is probably what I need
