Let dx ' 1 dy ' = dxı 1 dyı 1 . . . 1 dxk 1 dyk ; we interpret dx " 1 dy " and dx 1 dy in a
similar way . Then the complex orientation of CY2k + 1 is given by the ( 4k + 2 ) -
form dx A dy , and the complex orientation of CV is given by dx ' 1 dy ' .

In fact , Ka ( e ) is the rational curve given , in projective coordinates , by ( s , t ] - [
so , st ? + €83 , 3 + es ? t , ats ? ) . Theorem 2 . 8 ( ii ) implies that Cw ( Ka ( e ) )
changes by + 2 at a = 0 . Consequently , Cw ( Ka ( € ) ) # Cw ( K - a ( e ) ) for a = 0
