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.
