Two polynomial identities

(8 pages)

Abstract. We establish two polynomial identities. One of which generalizes a key identitie in ``A factorization theorem for classical group characters, with applications to plane partitions and rhombus tilings" by Mihai Ciucu and the first author [preprint 2008]. The other shows that the two sides in the identity can be expressed alternatively in form of a Pfaffian.
