Is it possible to obtain the inequality $\|\nabla f\|_{L^{2p}} \leq C (\|f\|_{L^\infty} \|f\...
Nirenberg's paper On elliptic PDEs claims that if a function $f$ on $\mathbb{R}^n$ tends to zero at infinity or is in $L^q$ for any $q < \infty$ then the "interpolation" inequality
$$

Sobolev interpolation inequality for relatively compact subdomains
I was looking at Nicolaescu's Lectures on the Geometry of Manifolds (3rd edition). In Theorem 10.2.29 he presents (without proof) the following inequality:
For $m \geq 1, p \geq 1, 0 < r \leq R$ there …

Deriving the general interior elliptic estimate from the compactly supported case
This is an exercise (10.3.4 in the third edition) from Nicolaescu's Lectures on the Geometry of Manifolds.
Let $L$ be an elliptic differential operator of order $k$ and $1 < p < \infty$. The book prov …
