3 that pl ( Â ( s ) ) = 0 almost everywhere on S . Thus , for almost all s , o vanishes
on the spectrum o ( Â ( s ) ) . So , for some set o , in { with eloo ) = e , the function
o vanishes on Uses , O ( Â ( s ) ) , and since y is continuous , it also vanishes on ...

Consequently , if we use Lagrange ' s rule to expand this 2v x 2v determinant by
minors of order v , we find that the expansion contains only two non - vanishing
terms . Thus our 2v X 2v determinant may be expressed as P2P , FQ1Q2 , where
...
