Now with yjk := Fk(xj), 0 ≤ j ≤ N, 0 ≤ k ≤ M, we get a partition of V into sets for 0 ≤ j ≤ N, 0 ...

for all ν with (8.2.90). Thus we would have (8.2.91) On the other hand, by (8.2.88), we may assume which in conjunction with (8.2.91) yields the contradiction Consequently, (8.2.89) must ...

Indeed for one has (E′ k, h) = (k, E′h) (exercise) and, since V(t) ⊂ K, clearly (u(t), E′(t)k) = (E′(t)u(t), k) a.e. Further, E′u ∈ L2(Ta, H), since, for ...
