... (28)
This i dentity is of the involution–type.
Proof. The left–hand side of (28) corresponds to superpositions of matchings µ ∪ ν of
non–vanishin g weight with red vertices R ∪ W and blue vertices ... image of χ is precisely
the set of superpositions of matchings corresponding to the right hand side of (28).
This yields immediately the following generalization of a res...

By a similar discussion as in the proof of (i), we may also show that (ii)-(iv) are true.
We omit the procedure here. This completes the proof of Lemma 2.9.
