论文摘要
令$ s_1 $和$ s_2 $为平行牵引的有限工会。我们描述了$ s_1，s_2 $和指数$ p $的必要条件，从而使$ pw_的规范投影$ p $从$ pw_ {s_1 \ cup s_2}^p $到$ pw_ {s_1}^p $是一种收缩。
Let $S_1$ and $S_2$ be disjoint finite unions of parallelepipeds. We describe necessary and sufficient conditions on the sets $S_1,S_2$ and exponents $p$ such that the canonical projection $P$ from $PW_{S_1\cup S_2}^p$ to $PW_{S_1}^p$ is a contraction.
