# Nica and Speicher: Lectures on the Combinatorics of Free Probability Theory

• A. Nica, R. Speicher: Lectures on the combinatorics of free probability, London Mathematical Society Lecture Note Series, Vol. 335, Cambridge University Press, 2006
• Here is a pdf-version by the authors of the book
• Every good book has its typos, so here are ours. It is quite likely that this list will grow over the course of time. The page numbers refer to the pdf-version.
• In Eq. (5.6): $\varphi(a_1b_2a_2b_2)$ should be $\varphi(a_1b_1a_2b_2)$ (page 81)
• page 94, second displayed equation: the second $a_1$ should be a $b_1$
• in Remark 6.10: ignore the “indexpositive!” (page 97)
• page 129, second displayed equation and the line before and the line after: $V_m=\{r\}$ should be $V_m=\{p\}$ and correspondingly $a_r$ should be $a_{r(p)}$
• page 179, line 4: $v_{s+1}=n$ should be $v_{s+1}=n+1$
• in Eq. (11.8): the subscript $\pi$ should be $\sigma$ (page 188)
• in Eq. (11.16): in the definition of the set on the left-hand side add that all blocks of $\pi$ are even (page 200)
• in Eq. (12.14): in the case $0\leq \lambda\leq 1$, the density part is $\tilde \nu$, and not $\lambda \tilde \nu$ (page 216)
• in Example 22.34, the cycle (4) is missing in $\gamma \pi$ (page 388)
