论文摘要
这些笔记涉及有关截断的一些最新断言,$ f \ mapsto | f | $和构图$ f \ mapsto g \ circ f $在空间中的$ a^s_^s_ {p,q}(\ mathbb {r}^n)$,$ a \ in \ in \ in \ {b,f \ \} $。
These notes deal with some recent assertions about truncations $f \mapsto |f|$ and compositions $f \mapsto g\circ f$ in the spaces $A^s_{p,q}(\mathbb{R}^n)$, $A \in \{B,F \}$.
