Abstract

Distances between homotopy classes of Ws,p(SN;SN) are investigated by researchers. It is demonstrated that the classes These classes are precisely the connected or path-connected components of Ws,p(SN;SN). The researchers obtain the order of magnitude of the distances dist Ws,p, and show that these results are not sensitive to the choice of a specific distance among various equivalent ones.
