• Section number:5.2.1

• Name: B.J.Buter
• Email: bjbuter [at] science [dot] uva [dot] nl
• Content: Definition 5.2.1 "I=..., equivalence relation" is not an equivalence relation. An equivalence relation is a collection of ordered pairs, thus if I_{i,j} were a relation, then where h \in I_{i,j} is written, h should be an ordered pair, this is not meant. I would rewrite as:"I=(I_1,...,I_n), where I_i={I_{i,1},...,I_{i,k_i}} is a partition of \{h\in H : \rho(h) = i\}, with I_{i,j} equivalence classes."

• Name B.J.Buter
• Email: bjbuter [at] science [dot] uva [dot] nl
• Content: Definition 5.2.3, item 2 equivalence classes are only defined for nodes where a player acts, according to definition 5.2.1. The restriction if \rho(h_j)=i should be added.

### The following errors are fixed in the second printing of the book and online PDF v1.1

• Content: Definition 5.2.3, using n as a counter is confusing since in other definitions n indicates the number of players.
