Streszczenie
This note aims at providing some information about the concept of a strongly proximal compact transformation semigroup. In the affine case, a unified approach to some known results is given. It is also pointed out that a compact flow $(X, {\mathcal S})$ is strongly proximal if (and only if) it is proximal and every point of $X$ has an ${\mathcal S}$-strongly proximal neighborhood in $X$. An essential ingredient, in the affine as well as in the nonaffine case, turns out to be the existence of a unique minimal subset.
