Density of smooth maps in W k, p(M, N) for a close to critical domain dimension

Original Paper


Assuming m − 1 < kp < m, we prove that the space C (M, N) of smooth mappings between compact Riemannian manifolds M, N (m = dim M) is dense in the Sobolev space W k,p(M, N) if and only if π m−1(N) = {0}. If π m−1(N) ≠ {0}, then every mapping in W k,p(M, N) can still be approximated by mappings MN which are smooth except in finitely many points.
