Some other corrections for Book I:
- P. 34, in the 3rd line, $L^{p_j}(X_j)$ should be $L^{p_j}(X)$.
- P. 115, in the 5th line, $|\xi_{j_0}|>|\xi|/\sqrt{n}$ should be $|\xi_{j_0}| \geqslant |\xi|/\sqrt{n}$, since we can not exclude strictly the case of =, e.g., the cube.
-
P. 128, in the 5th line from below, "$M>2|\alpha|$" should be "$M>2\max(|\alpha|,n)$", since it is necessray to prove the convergence of the integral over the complement of the cube.
-
P. 129, in 2nd line, it is enough to replace "$(1+|x-y|)^M$" by "$(1+|x-y|)^{M/2}$".
-
P. 130, in 8th line, the "+" symbol between two integrals should be "-".
-
P. 319, 6th line from below, I think that "Theorem 1.4.19" might be replaced by "Theorem 1.3.2 with $p_0=1$ and $p_1=2$, and Remark 1.3.3 since $H$ is linear". This is only a suggestion, since Thm 1.4.19 was not taught as the suggestion in preface (1.1,1.2,1.3,2.1,...) which is in Section 1.4.
-
P. 321, 6th line from below, "$\|H(f)\|_{L^{2p}}<\infty$" should be "$\|f\|_{L^{2p}}<\infty$". By the way, in the inequality just above this line, it is maybe better and more readable to take square for each side.
-
P. 322, 8th line, "$0
-
P. 327, in the 2nd line, it is better to omit "$|\xi|$" in the denominator because it has been assumed to be 1.
-
P. 344, in the 10th line, $\frac{dr}{r}$ should be $dr$.
-
P. 346, in the 10th line, $\Omega\in L^1$ should be $\Omega_j\in L^1$.
-
P. 347, Theorem 5.2.11 should be added the condition "$n\geqslant 2$" because some estimates are not valid for $n=1$ in the proof.
-
P. 349, in the 6th line from below, $\Omega()$ should be its absolute value $|\Omega()|$.
-
P. 350, in (5.2.39), $\max(p,(p-1)^{-1})$ should be $\max(p^2,(p-1)^{-2})$.
-
P. 352, in the middle long inequalities, $F_j(z)$ should be $G_j(z)$ or $F_j(z/\varepsilon)$; similarly, in next line $F_j(r\theta)$ should be $G_j(r\theta)$ or $F_j(r\theta/\varepsilon)$.
-
P. 352, in (5.2.45), $\max(p,...)$ should be $\max(p^2,...)$.
-
P. 352, Corollary 5.2.12 should be added the condition "$n\geqslant 2$".
