- A compact Hausdorff set K is called Rosenthal-Banach compact, if there is a polish space X and a Banach space E so that K is homeomorphic with a compact subset of B_1(X,E) in the topology of pointwise-weak convergence?, where B_1(X,E) is the set of functions which there is a sequence continuous for every n ∈ N, such that if t ∈ X then
