Streszczenie
Let $X$ be a completely regular Hausdorff topological space and $C_{p}(X)$ the space of continuous real-valued maps on $X$ endowed with the pointwise topology. A simple and natural argument is presented to show how to construct on the space $C_{p}(X)$, if $X$ contains a homeomorphic copy of the closed interval $[0,1]$, real-valued maps which are everywhere discontinuous but continuous on all compact subsets of $C_{p}(X)$.
