This continues my series of books derived from my blog. The preceding books in this series were “Structure and Randomness“, “Poincaré’s legacies“, “An epsilon of room“, “An introduction to measure theory“, and “Topics in random matrix theory“.

An online version of the text can be found here.  It is based primarily on these lecture notes.

Errata:

• Page ???: In Exercise 1.1.17, $1/\sqrt{N_0}$ should be $1/\sqrt{N}$.
• Page ???: In Exercise 1.1.20, $\delta^{-C_d} N$ should be $\delta^{C_d} N$.
• Page ???: after (1.9), “left-hand side of (1.8)” should be “left-hand side of (1.9)”.
• Page ???: Near the start of Section 1.3.2: the $c_i$ should be elements of $G$ rather than ${\bf Z}$.  “equilently” should be “equivalently”.
• Page ???: In Exercise 1.3.8, $a_1=-a_2=-a_3$ should be $a_1=a_2=-a_3$.
• Page 98: In the definition of a nilpotent filtered group $G_\bullet$, the additional hypothesis that $G$ is also nilpotent is required (this is automatic in the most important case $G_{\geq 0} = G_{\geq 1} = G$, but not in general).
• Page 100: In the first paragraph, replace “starting from a point” with “starting with the base group $G/G_{\geq 1}$, which is a point in the most important case $G_{\geq 0} = G_{\geq 1} = G$“.  Similarly, after Exercise 1.6.14, replace “starting from a point” by “starting from the base space $G/(G_{\geq 1}\Gamma)$, which is a point in the most important case $G_{\geq 0} = G_{\geq 1} = G$“.
• Page 109: In Exercise 1.6.22, the argument indicated only works under the stronger hypothesis that $\alpha, \beta, \alpha \beta$ are linearly independent modulo 1 over the integers.  (To handle the general case, one either needs the more complicated quantitative (single-scale) relative van der Corput lemma in my paper with Green, or else rely on the ergodic theorem as was done in the paper of Leibman.)
