 note = {Let Top and Diff be the categories of topological and diffeological spaces, respectively. Then there is a functor D : Top → Diff which maps a topological space X to the diffeological space DX. We define the homotopy groups of topological and diffeological spaces, respectively. In this paper we shall show that πn(X, x) and πn(DX, x) are isomorphic, where X is a topological space.},
