Even if Milnor formulates Theorem 4 for the integer class $p_1$, the given proof only uses the rational one (so he proved more then formulated). Because of this, it is fair to say that invariance of the integer $p_1$, however interesting by itself, is irrelevant to this paper of Milnor. (The rational Pontryagin classes were shown to be topologically invariant by Novikov in 1966.) | |
