Let $(M,g)$ be a complete Riemannian $m$-manifold, with bounded geometry and $m\geq2$. Suppose that $(M,g)$ admits a bounded geometry. **Q** Can we show that for $k-\frac{m}{p}\geq l-\frac{m}{q}$, we have a continuous embedding $$L^p_k \hookrightarrow L^q_l?$$ PS: I think it is true, at least for the equality as in the Aubin's book. I do not how to show the embedding for the inequality case(assuming the equality case is true)?
