Please let me know if you find errors or typos! Here are the ones that I'm aware of.
• p.5, bottom of page: maps whose kernel and range are in $F$'' should read maps vanishing on $F$ and with range in $F$''.
• p.9, top of page: Hence R_1R_2-R_2R_1'' should read Hence R_1R_2=R_2R_1''.
• p.98, first displayed formula in proof: $(I + DE_1)T$ should read $(I + E_1D)T$.
• p.99, first displayed formula of section 4.3.2.: $B^\flat\circ g(A)$ should read $g(A)\circ B^\sharp$.
• p.100, after Theorem 4.2: In the sentence Once again, while'' skip Once again''. The phrase below'' refers to Theorem 4.4.
• p.123, middle of proof of Lemma 5.3: for $k\neq 0$'' should read for $k\neq 1$''.
• p.150, first displayed formula: $L(\xi)$ should read $L_\wedge(\xi)$ .
• p.165, beginning of proof: By applying the operator $\exp(-\frac{1}{2} \sum_a [..])$'' omit the $\frac{1}{2}$.
• p.168, beginning of proof: degree 2'' should read degree 3''.
• p.169, second displayed line from bottom: The plus sign should be a minus sign.
• p.200, bottom of page: $w\mathfrak{t}_+\supseteq \mathfrak{t}_{\mathfrak{k},+}$ should read $w\mathfrak{t}_+\subseteq \mathfrak{t}_{\mathfrak{k},+}$
• p.204, displayed formula after (8.9): The middle equation should read $.. (V\otimes \mathsf{S}_{\mathfrak{p}}^{\bar{1}})/\ \mathcal{D}_V (V\otimes \mathsf{S}_{\mathfrak{p}}^{\bar{0}})=..$
• p.205, Remark 8.10: triplets'' should read multiplets''.
