Problems on Hyperspace Retractions
Unsolved problems concerning hyperspace retractions for curves, dispersed in the literature, are recalled and discussed, and various interrelations between them are indicated. A particular attention is paid to retractions satisfying some additional conditions, to continuous selections on the hyperspace of subcontinua of a given curve, and to associative means, understood as a special retraction on the hyperspace of the at most two-point sets.
