Poincare inequality and Friedrich lemma.


roposition

(Friedrich lemma) Suppose $U~$ is a bounded subset $\QTR{cal}{R}^{n}$ with the diameter $d$ and $1\leq p<\infty$ . Then MATH

Proposition

(Poincare inequality) Let $U$ be a bounded, connected star-shaped open subset of $\QTR{cal}{R}^{n}$ with $C^{1}$ boundary and $1\leq p\leq\infty$ . Then MATH where the constant $C$ depends only on $n,p$ and $U$ .

Proposition

(Poincare inequality for a ball) Let $1\leq p\leq\infty$ . Then MATH where the constant $C$ depends only on $n$ and $p$ .
