The correct analysis <strong>of</strong> the // - phase is more subtle.<br />
One subtlety is that the are not massive<br />
everywhere.<br />
φ i<br />
Write<br />
W = ∑ a<br />
p a Q a (φ) = ∑ ij<br />
φ i A ij (p)φ j<br />
then they are only massive away from the locus<br />
{det A = 0} ⊂ P 1<br />
But that just makes th<strong>in</strong>gs more confus<strong>in</strong>g....
