The Ruziewicz problem, named after the Polish mathematician Władysław Ruziewicz, concerns the existence of a certain type of topological space known as a "sufficiently large" space that can be mapped onto a simpler space in a specific way. More precisely, the problem addresses whether every compact metric space can be continuously mapped onto the Hilbert cube.
