• Content: The condition in Definition 3.5.1 is wrong. It should read:
\begin{multline*}
\sum_{d \in D} \pi(d) u_i\left(\sigma_1(d_1),\ldots,\sigma_i(d_i),\ldots,\sigma_n(d_n)\right) \\
\geq \sum_{d \in D} \pi(d) u_i\left(\sigma_1(d_1),\ldots,\sigma'_i(d_i),\ldots,\sigma_n(d_n)\right).
\end{multline*}

That is, the RHS of the inequality should use \sigma' only for player i, and \sigma for the other players.

• Content:capital S (denoting a strategy) should be replaced by a lowercase s, for consistency with the rest of the book.

• Name:Ulle Endriss
• Content: In Definition 3.6.1 (trembling-hand perfect equilibrium), the uppercase S's should be replaced by lowercase s's, as they all denote profiles. The first sentence of the definition should start with "A mixed-strategy profile s..." (not "A mixed strategy S...").
