## Density of smooth functions between two manifolds in Sobolev spaces.(English)Zbl 0657.46027

Author’s summary: We give some results concerning density or non-density of smooth functions between two compact manifolds $$M^ n$$ and $$N^ k$$ in Sobolev spaces $$W^{1,p}(M^ n,N^ k)$$. In particular, we study the case $$N=S^ k$$.
