Je vyšetřována souvislost mezi složitostí funkce f z polského prostoru X do polského prostoru Y a složitostí množiny C(f) = {K: f|K je spojitá). (cs)
We investigate connections between complexity of a function f from a Polish space X to a Polish space Y and complexity of the set C(f) = {K: f|K is continuous).
