Opis:
Two classes of topological spaces are \emph{equivalent} if every member of one
class has a homeomorphic copy in the other class and vice versa. We say that a
class of metrizable compacta $\mathcal{C}$ is \emph{compactifiable} if there
is a continuous map $q\colon A \to B$ between metrizable compacta such that
the family $\{q^{-1}(b): b \in B\}$ is equivalent to $\mathcal{C}$.
I will present several results from the joint work with J. Bobok, J. van Mill,
P. Pyrih, and B. Vejnar arxiv.1801.01826.
