Popis: Let X be a compact metric space and let 2 X {2^X} be the space of all nonvoid closed subsets of X topologized with the Hausdorff metric. For the closed unit interval I the authors prove that 2 I {2^I} is homeomorphic to the Hilbert cube I ∞ {I^\infty } , settling a conjecture of Wojdyslawski that was posed in 1938. The proof utilizes inverse limits and near-homeomorphisms, and uses (and developes) several techniques and theorems in infinite-dimensional topology.
